Selena Gomez wore the ultimate 'rich mom' matching lounge set — get the look for $40

Loungewear looks luxe — one might even say "rich-mom" luxe — in simple neutrals. Even though this sleeveless set is loose-fitting and casual, when worn together it's giving a polished, I-wake-up-like-this vibe. This pale apricot hue is a dream, but there are over a dozen options.

One shopper raved, "I wore this on a 9.5-hour plane ride and it was so comfortable. It can be worn casual or [you can] add different jewelry and heels and it can be for a dressy occasion. Would definitely buy again."

Made from a nubby, stretchy fabric, this crewneck sweater has an oversize fit. The sleeves are extra long for added coziness, and the hemline hits well below the bum for plenty of coverage. Choose from four colors in sizes XS-3X. Be sure to check out the matching pants as well.

Shoppers who've snagged this plush outfit say it's super soft and warm. Wear it while relaxing at home or for your morning Starbucks run. It comes in 17 colors in sizes S-XXL. Before you hit the buy button, two important notes: The pants run long, and the set can only be hand-washed.

"If you cannot afford the higher price tag of Barefoot Dreams, these are a great 'knockoff' version ...," one customer shared.

Mocha mousse is the must-have color of the season, so don't think twice about adding this pick to your wardrobe. It's less than $50, but people who've purchased it say it's high-quality, comfortable and stylish. 

"I wasn’t sure what to expect, but this set seriously delivers," one reviewer explained. "The knit is soft without being flimsy, and the pants actually have length, which is rare. It looks super put-together for something so comfortable — easy to dress up or down. I wore it on a travel day and felt cute the whole time."

P.S. If you're not sure the brown will suit your skin tone, there are more than 15 other shades up for grabs.

Over 2,000 Amazon shoppers have given this machine-washable sweatsuit a five-star rating. The wide-leg pants are flattering and forgiving, while the deep V-neck sweater looks good on its own or with a tee layered underneath.

"I absolutely love the fabric on this lounge set. It's super soft and stretchy and doesn't show every lump and bump on my body, which makes it very flattering," one commenter wrote.

Another added, "This set is exactly what I was hoping it would be! The quality of the construction and the fabric itself are both great. The fit is so nice in every area, and the color is gorgeous! They are super comfortable.... Soft, perfect thickness that keeps you cozy while not making you overheat."

If you haven't touched Old Navy's SoSoft fabric, you need to change that. It's as soft and luxe as cashmere, but for a fraction of the price. This tunic-length sweater has hundreds of five-star ratings, with customers sharing that it's slimming and easy to wear. Both the top and the matching pants are available in sizes XS-4X and have a ribbed texture that's a hallmark of the "rich mom" aesthetic.

Available in four neutral colors, this loose-fitting sweater is made from Gap's bestselling, cotton-blend CashSoft material. The generous fit is perfect for layering, and the size range is impressive. Choose from regular, tall and petite fits in sizes XXS-XXL. There are also matching pants, and yes, they're just as comfy and cozy as the sweater. Right now, you can get 30% off both with code GREAT. 

If you're able to splurge, then this 100% cotton duo should be on your radar. The Henley button details on the top, the cropped, not-too-wide pants and the waffle texture all make this set feel a little more elevated than some of the more casual styles you'll see. It's currently available in two colors — black and white — but don't wait to buy because sizes are selling out quickly.
