• ThirdLove's loungewear and sleepwear match the comfort, price, and style of its famed lingerie line.
  
• Sizes range from XS-3X and prices range from $15 to $154, with kits that combine basics for less.
• I tested several bestsellers and my favorite was the Knit Jogger for its cloud-like comfort.

Lingerie startup ThirdLove brings inclusion to an industry saturated with standard sizes, introducing a range triple the options of other brands. Their latest move? Loungewear. Coming in sizes XS-3X, the pieces combine the affordability, comfort, and style that we love from the brand's bra collections.

Though ThirdLove isn't entirely new to loungewear, it recently re-launched in February under a new name: Lounge by ThirdLove. The line expands on the previous selection with a number of new loungewear styles and sleepwear basics. Now you'll find everything from silky smooth joggers to chic lounge sets, and a color palette made up of mostly soft neutrals. Prices range from $15 for a pair of Pima Cotton underwear to $154 for a loungewear and bra kit.

Insider Reviews has been testing ThirdLove since 2017 and it currently holds the top spot in our guide to the best bras you can buy. Half-cup sizes helped put ThirdLove's name on the map, but the label continues to make bras more accessible than ever, carrying over 80 sizes and counting. It also doesn't hurt that they offer a 100% fit guarantee and their stellar customer service makes purchases stress-free.

To see if the loungewear lives up to our feelings about the bras, ThirdLove sent me some of its bestselling pieces to test out. My favorite was the ultra-comfy Knit Jogger and my favorite set was the French Terry pairing, but I also appreciated the Woven Button-Down Shirt and Woven Pant set for its fashionable take on loungewear. You can find my full thoughts on each style, below.

My review of Lounge by ThirdLove

Knit Dolman Tee

How it fits: True to size, but size down for a snug fit.

ThirdLove's Knit Dolman Tee offers a contemporary take on a basic lounge tee. The fit was oversized on me, with a drapey silhouette that borderlines on baggy. Made from a cotton-spandex blend, the shirt felt smooth and cool against my skin. The scoop neckline opened a bit too wide on my neck, so it tended to shift more toward one shoulder. The back of the shirt features a box pleat that elevates the plain look of the tee. This muscle-tee-like shirt doesn't rank high for me in comparison to other styles on this list, but I like it more when it's paired with the knit joggers. It comes in two colors: black and burnt orange.

Knit Jogger

How it fits: True to size.

The Knit Jogger matches the same super soft fabric as the Knit Dolman Tee; it feels like I'm wearing a cloud on my legs. The pants rest comfortably on my hips and ankles and, even though the waistband isn't adjustable, I never find myself tugging them up. Unlike other joggers I've tried, these don't trap in heat. They feel weightless all day and the silhouette keeps its same slouchy fit. To top it off, the two side pockets have enough depth to throw in my lip balm and eye drops. I could live in them for days.

French Terry Sweatshirt

How it fits: It fit me quite snug, especially after washing; size up for extra room.

The fitted French Terry Sweatshirt comes in a beautiful cream color I'm happy to wear for a day with multiple video calls. But if you're not partial to the cream, it also comes in black and olive. The textured side panels elevate the basic sweatshirt while its classic crewneck design makes it easy to layer with jewelry or throw an oversized coat on top. It's not as soft as the fabric I'd typically expect from loungewear basics, but it does offer a breathable terry that I feel comfortable sleeping in. I only wish I'd sized up so I could layer a T-shirt underneath.

French Terry Short

How it fits: True to size, but the length is on the shorter side.

The French Terry Short offered a relaxed fit that cinches to your waist with a pull of the drawstrings. I'm absolutely in love with the cream color and the raw hem; it feels stylish even when working remotely. Combined with the French Terry Sweatshirt, this earned the spot as my favorite ThirdLove loungewear set by far. Both pieces feature the same type of loose, airy fabric as the sweatshirt. And its deep pockets were a major plus for me. I probably wouldn't take these shorts beyond my home because they fall quite short, but I'd still order true to size because they may be too wide a size up. The care instructions recommend laying flat to dry, which is sage advice because I did otherwise and they shrank slightly.

Woven Button-Down Shirt

How it fits: True to size, but I recommend sizing up if you prefer a baggier fit.

With ThirdLove's Woven Button Down, I can look professional from bed. The drop shoulder and folded lapel gave me a structured fit, while the three-quarter length sleeves hit my forearms and kept it from looking too pajama-like. I thought the woven fabric felt too stiff to work as a PJ, so I saved it for daywear. I see it becoming a versatile option in my closet that I can style with denim shorts or leave unbuttoned over tank tops. You can definitely size up if you prefer a roomier fit.

Woven Pant

How it fits: True to size; size down if in between sizes.

When paired with the button-down, the Woven Pant makes lounge suits a thing. The cropped ankles have an Audrey Hepburn-esque look, and there's a stretchy waistband that feels non-constricting. There are no strings to tighten the waist, so the size small (my typical size) fit slightly big on me. The pants wrinkle quite easily and the black fabric I chose collected lint, so if you're looking for less maintenance, I'd opt for the striped pattern option. I wouldn't call the fabric uncomfortable, but combined with the woven top, it doesn't allow a lot of movement — a sacrifice that gives it the structured look. ThirdLove also has a woven short that might create a better balance.

Adjustable Strap Wireless Bra

How it fits: True to size, but the straps loosen throughout the day.

ThirdLove's Adjustable Strap Wireless Bra is the only bra I'd ever wear to bed, partly because I forget it's even on. Its nylon-spandex blend feels silky smooth against my skin, and even if I'm wearing it in the Florida humidity, it keeps much cooler than other wireless bras I've tried. I'd choose it for comfort over support and style. Its light padding offers some support in lieu of an underwire — but the foam cups bulge out from the material. The sleek material and straps loosened throughout the day, so I had to tighten the straps almost all the way. However, I wouldn't size down in fear of the cups being too small. Some customers said that it doesn't hold up well in the wash. But, I washed mine and laid it to dry and it kept its same shape.

The bottom line

ThirdLove's loungewear and sleepwear collection proves the label can do more than just lingerie — and do it well. Although some pieces hit the mark more than others, there's no doubt ThirdLove's loungewear endeavor is just the first few steps in a fun, inclusive new approach to the category. If you're looking for comfortable yet elevated pieces, then we recommend Lounge by ThirdLove.
