Matchy-matchy! These are the best lounge sets to shop at Amazon this winter

This baby looks just like Oprah's favorite Spanx lounge set — which is my fave as well! I love my set so much I've been thinking of getting another until I found this way more affordable look-a-like. Instead of spending that $200-plus splurge, I think I'll just snag this instead. The bestseller comes in over 20 colors, and shoppers say it's incredibly soft and stylish (just like its more expensive counterpart).

"I'm shocked at the amazing quality. So silky soft with stretch. Perfect for travel or lounging," said one shopper before adding, "I plan to buy in other colors."

It's rare that you can use "polished" and "relaxed" to describe the same outfit, but this set has somehow hit that often-elusive mark. The warm knit is accented with sophisticated tortoise-shell buttons, adding a refined touch to the top for an effortless look that still exudes loads of style. The elastic waistband on the pants makes for a comfortable fit, so you can feel free to unwind without compromising on elegance.

"Perfect set for winter guys — price is also so affordable. Material is so very nice, comfortable, soft and smooth," raved one shopper.

More than 13,600 effusive five-star reviewers have helped make this adorable sweatsuit a top seller, and we're big fans too. The machine-washable set comes in over 30 hues (some with white "racing" stripes) and sizes small to 3XL. The bottoms have pockets to hold your essentials and a tapered leg for a flattering effect.

"I have purchased this set in three colors at this point," said one mega-fan. "The material is so soft and comfortable, it feels like wearing pajamas but the material quality is nice enough that you look fashionable and cute out in public. It's hard to find a set where both the top and bottom fit, and this set hits the mark."

A sleek turtleneck and wide-leg pants are always effortlessly chic — just look at this set. The gold buttons on the cuffs give the top an elevated, expensive feel, and the drawstring waistband on the pants will keep you cozy. The hardest part is choosing from the 16 colors (honestly, we might just get two — don't judge).

"I have received so many compliments on this … it is literally the most comfortable thing I have ever worn," raved one shopper.

This V-neck number's ribbed knit top and high-waisted pants complete its casual-chic, vaguely retro vibe, and you'll be psyched to combine the pieces with other chillax-time all-stars in your wardrobe.

"My new favorite comfort outfit," wrote this buyer. "Honestly, I have gotten comments out in public about it being a nice set. The sleeves are nice and the neckline is comfortable. The material is comfortable and the pants have a nice stretch to them. Not too thick or thin. Great material, great quality."

Who doesn't love to slip on a hoodie on chilly mornings? This one comes with matching cargo sweatpants for a casual, stylish look. Bonus: It's machine-washable.

"I just love the softness of this outfit and the pockets," wrote one reviewer. "I for one am always losing things, and just love all of the pockets to tote around my phone, keys and other things without having to grab my bag."

The ribbed material on this set makes it look more polished than your average sweatsuit. The relaxed silhouette offers a cozy fit with plenty of room to move, while the thick fabric keeps you warm. (No wonder reviewers say it's the perfect travel outfit.)

One raved, "This is a perfect set for so many uses; traveling, running errands or even at home. It's soft and has a nice weight, not too thin at all. Holds a good shape and flattering on the body."

We love any outfit that 1. doesn't take any thought 2. looks effortlessly chic and 3. makes us look way richer than we are. This high-contrast set checks all three boxes. The trim looks so polished, plus the wide-leg pants and quarter-sleeve top make it versatile. Wear it with flats on a flight, with heels once you reach your destination or — even better — slippers while diving into your next bestselling read. The material is lightweight and stretchy, which means it'll take you right through spring. 

"The best two-piece comfy and easy sweatsuit! Can dress up or down! Super cute on. I ordered true to size and the fit was great. Worth every penny! Ordered multiple colors," said one shopper.
