Promising review: "Buttery soft is an understatement! This two-piece set is so unbelievably soft and comfortable! I honestly feel like I’m wearing a cloud!!! I’m 5’9 150 pounds, and I’m wearing medium. Could size down to a small, but I like the oversize look for comfort. It’s not super thick, which I love because I’m always hot! The color I have is sage green, and it’s perfect for fall and winter! I’m certain this outfit will last as long as I need it to! The material is fantastic! 1,000% recommend this item." —Dana Merida

Promising reviews: "Soft, warm sweater knit. I’m so glad I got this set! It’s like putting on a warm hug when I get home from work. ;) And you can wash it in the washing machine and dry it in the dryer, hooray! I’m 5’7”, 120 pounds: medium fits with a slouchy look. This is perfect for after work and before pajamas." —Mrs. Movement

"Been wearing this since I received it, and I have to say I am obsessed. The fabric is so nice, and I've gotten so many compliments on it from random people. I need it in every color at this point!" —Kindle Customer

Get it from Amazon for $47.58+ (available in sizes S–XXL and 14 colors). 

Promising review: "I want this set in every color. They are super comfy. If you like to sleep in clothes but hate getting hot, this is a great set. If you just want something to lounge around in, it’s also perfect for that. I’ve washed them many times, and they’ve shown no signs of wear." —India

Get it from Amazon for $24.99+ (available in sizes XS–XXL and 10 colors). 

Promising review: "Perfect outfit to dress up or down with sandals or sneakers. I bought this for a trip to Greece to wear while shopping. It was very comfortable. I also like how I can wear the pieces separately!" —Cori

Get it from Amazon for $29.99+ (available in sizes XS–XL and 23 colors). 

Some reviewers find that this set runs big, so consider sizing down!

Promising review: "Love, love, and love this matching two-piece set. It runs true to size, is very warm, and is not heavy. This is a set that can be worn around the house, a set to be worn running errands or heading out to a sports game, or just whatever you want. This outfit is just super cute, hands down, great value for the money. I even get asked every time that I wear it about where I purchased it. (Thank you, Amazon.) I will be ordering it in a few other colors." —Cee Banks

Promising review: "Cute set that is very comfy and perfect for travel. I wore it for 40+ hours and felt comfortable the whole time. Love the bright color and the soft material. The ribbed cotton style fabric looks nice and not cheap like some other fabric types can. The pants are long (I'm 5'2") but high-waisted enough that they can just be pulled up, and this also gives more coverage with the cropped top. Highly recommend, and I will get this in more colors. Do make sure you wash it by itself in cold water the first time, as the color does run at first. It's fine now." —Lucy Marie

Promising review: "I was pleasantly surprised by the amazing quality and perfect fit of this outfit! The material feels high-end, and the style is super trendy. It’s the perfect sporty-chic set for running weekend errands, grabbing coffee, or just lounging around the house in comfort. I’ve gotten so many compliments already — definitely worth every penny!" —Kim Simpson

Promising review: "This was cuter than I expected. It’s slightly oversize, and I love it like that! I got a size small. I’m 5 feet, 110 pounds, and I probably could have gotten an XS too, but I left room for shrinkage and the boho oversize feel. I bought mine in the cream color, and it is super comfy and adorable. The pieces can be worn separately as well. Two thumbs up!" —Anonymous

Get it from Free People for $98 (available in sizes XS–XL and six colors).

Promising review: "This outfit exceeded my expectations. It is super soft and more of a sweater material than a traditional sweatsuit material. Will be ordering this in additional colors. This is the perfect casual outfit to wear when visiting friends for a home get-together or for just lounging around the house when you want to be warm and comfortable." —Mrs LG

Get it from Amazon for $37.59+ (available in sizes S–XL and 20 colors). 

Promising review: "Beautiful set, super comfortable, and excellent quality. The fabric is soft, not transparent, and the striped design with a collar gives it a modern and elegant touch. Ideal for being at home or going out casually. The size corresponds perfectly. I loved it, I recommend it 100! 💯" —Liz Salazar

Get it from Amazon for $33.99+ (clip the coupon on the product page to get this price in select colors/sizes; available in sizes S–XXL and 11 colors). 

Promising review: "Love this outfit. Weekend at Bernie’s. Or maybe I had this same outfit when I was 8. It’s comfy, summery (or vacation-y), love the collar. I’m usually a large, but medium fits well. The waistband was slightly more snug than I’d usually prefer, but if I had gotten a large, I think it would've felt too big." —Anna H

Get it from Amazon for $48.99 (available in sizes XS–L and 29 colors). 

Promising review: "Love the fit and material! The color is vibrant and so pretty. It’s a softer knit material and thin but definitely not see-through! I’m 5’4”, 130 pounds, with an hourglass shape and got a size small. It fits oversize in the best way! The shorts are a bit long in the crotch, so I rolled the waistband to give them a shorter look — worked perfectly. Loved the set so much, I’ll definitely be buying more colors!" —Conrad

Get it from Amazon for $42.99 (available in sizes XS–XL and 26 colors). 

Get it from Victoria's Secret for $64.95 (available in sizes XS–XL and in fig). 

Promising reviews: "This outfit is amazing, and I got sooooo many compliments on it!! Like, tons everywhere I went. It is super soft, super comfortable, and seriously great quality. They were a tad long on me. Can’t say enough about it!! I’m buying more colors." —Nicole

"This pants set fits perfectly!! Got a great fit with my curves. I can wear this casually or dress it up for an elegant event!! Will definitely recommend and purchase again, in a different color. 😀" —Amazon Customer

Get it from Amazon for $39.99 (available in sizes S–XXL and 14 colors).

Promising review: "I just recently received this set, and I'm kind of obsessed! I washed, dried, and wore it, and so far so good! It held up fine during the laundry cycle. The fabric is soft and comfortable, which really impressed me because I believe it's made of polyester (which I normally shy away from). The fit is a bit oversize, which I appreciate, and I think it's fairly complementary given the fact that I'm a thicker girl. I was hesitant to spend almost 50 bucks on a shorts set, but I'm glad I did, and I'm already thinking about getting another color!" —ItsJustMe

Get it from Amazon for $32.29+ (available in XS–3XL and 35 colors/patterns).

Promising review: "For those of you who like to go to Walmart in your PJs and flannel pants, order this set! You will still be comfy but look great. These sets are lightweight but not see-through. True to size without fitting skintight. Extremely comfortable and versatile. Dress it up or down." —-Mimi-

Get it from Amazon for $22.99+ (available in sizes S–3XL and 40 colors/styles).

Get the bubble jacket from Skims for $88 and the bubble shorts for $54 (available in sizes XXS–4X and three colors). 

Promising reviews: "I wore this to Universal for my birthday, and I actually got two compliments on it! Not only was it lightweight to stand the heat, but it was also incredibly comfortable! I love the elastic waistband as it didn’t roll, and it also didn’t shrink in the dryer! Love love love it. Definitely buy it if you’re on the fence! And true to size." —Ashtyn Geisler

"Super cute set. Dress up or down. Great for travel or running errands. Great quality." —Amazon Customer

Get it from Amazon for $19.99+ (available in sizes XS–XL and in 12 colors).

Promising review: "I will be buying more of these because it feels and looks so good. For the bigger women like me who are afraid it won’t fit because it says 2X, give it a shot! I’m 5’6 and over 300 pounds. The 2X fits fine. I haven’t felt this pretty in a while. This pink really complements my tone, and the fit really complements my figure. I got so many compliments while wearing this. I would highly recommend. The fabric feels great, I don’t mind the price, the quality is good." —Anne White

Get it from Amazon for $41.99 (available in sizes S–XXL and 35 colors/patterns).

Promising review: "The two-piece set is very cute and comfortable. I wore it to my grandparents' birthday dinner and received many compliments. I wasn’t sure if it would be too long or too short, but it’s an even length. It might be longer on ladies who aren’t as curvy as I, with less booty, hips, and thighs. But overall, I think you’ll like it." —EmDeJai

Get it from Amazon for $40.99 (available in sizes S–XXL and 26 colors).

Get it from Boohoo for $56 (originally $140; available in sizes 12–26).

Promising review: "I got this set in royal blue. It fits true to size. They are beautiful, so comfy, and wash well. They are not even wrinkled out of the dryer. They are a little cooler than I expected. I thought they might make me too hot while sleeping, but they don't! These are really perfect PJs in my opinion." —JBS

Get it from Amazon for $19.99+ (available in sizes S–XXL and 44 colors/prints).

Promising reviews: "Super soft and comfortable to wear. I look forward to putting my pajamas on at the end of the day (or anytime on weekends). I have extremely sensitive skin, and these are so soft and comfortable." —Tinker

"It was wonderful. I loved it so much, I have ordered two others after I was given one as a gift from my daughter. I now have three of them in black, lavender, and cream. They are beautiful and comfortable to wear." —Ruthann Stephens

Get it from Amazon for $22.36+ (available in sizes S–3XL and in 35 colors).

Promising review: "Let me just start by saying that I am always pretty skeptical about buying clothing off sites like Amazon. I bought this set for a bachelorette party in Tahoe. The location is important because I was not sweating my tushy off in the heat wearing these. I tried this PJ set on, and it was instant love. The material is super stretchy and also provides a good amount of porosity. I can't provide a picture because I always look like a hot mess before bed. I love them and have been recommending them to everyone who has asked about them." —shayla patton

Get it from Amazon for $25.99 (available in sizes XL–5XL and 16 colors).

Promising review: "I am in love. The sizing is perfect. It’s comfortable. It fits perfectly. The color is incredible. Need in every color." —Sierra Perambo

Get it from Amazon for $14.99+ (available in sizes S–XXL and 15 colors/patterns).

Promising review: "Color, fit, material. Just what I was looking for in a comfortable set to travel in." —Sheryl's Pick

Get it from Amazon for $14.99+ (available in sizes S–XXL and 31 colors).

Promising reviews: "Love the neutral color and how stretchy and soft the fabric is! I love the baggy feel, it feels great on the waist, but a little long, which I actually like!" —Alesya Murza

"I’m not usually someone who can buy clothing in sets because my top and bottom halves are wildly different sizes, especially with how different every style and size fits. So when I saw this, I was super skeptical, but I also really, really wanted to give it a try, and I AM SO GLAD I DID. It is comfortable, cute, and so versatile. I dressed it more casually for a day out in Europe, but I can’t wait to wear it with some wedged boots too for a more dressed-up look. The fabric is perfect for the fall transition as it’s not thin, but it’s also not super heavy. I’m 5’5” 170lbs for reference, and I got a large! I’m wondering if I could fit in a medium, though, as it was very oversize." —Lindsay P

Get it from Amazon for $26.99+ (available in sizes XS–XL and 27 colors). 

Promising reviews: "This is the ultimate Aritzia-esque high-quality sweatsuit. It fits well, and the color is very true to the photo. It’s soft but also has a bit of weight and structure. I cannot recommend this style enough." —Jessica Robinson
