ThirdLove's cotton T-shirt bra is so comfortable you'll forget you're wearing it — here's how it's held up after one year of testing

This is a super comfortable bra — and perfect for everyday wear. For the price, I wish it were a bit more attractive (for example, a decal or something in the center by the cutout). The cups run a bit large, so if you're in between cup sizes, I would recommend sizing down. However, the band size is perfect and there's a comfortable amount of stretch.

One-Year update: My ThirdLove has held up very nicely — I handwash all of my bras cold, including this one, so I find that holding up over a year plus is fairly standard. The band hasn't stretched too much either. A footnote is that I probably wear it once every two to three weeks, so it's not in my heavy rotation.

The 24/7 name is no exaggeration: You really will want to wear this great everyday bra all the time because of how soft and comfortable it is. The memory foam cups fit closely to your chest and they're cut to an attractive shape that should work under most types of fabrics and clothing styles. Personally, I could do without the extra band because it tended to fold over onto itself whenever I wasn't standing or sitting completely straight; however, I do have a smaller chest and I assume it's there for support reasons. Either way, I still love this reliably comfortable bra.

I think the sign of a good bra is that it's comfortable enough that you barely realize it's there and you're not itching to take it off the moment you get home. The 24/7 Cotton T-Shirt Bra from ThirdLove delivers on that, with a simple style and soft feel that you'll enjoy wearing every day. The thin cups are comfortable and also form-fitting, so you don't have to worry about any of those annoying outlines under your shirt. I sometimes opt for a larger band size, but I decided to stick to a 32, although I was a little skeptical. I was pleasantly surprised at how comfortable the band was and how smoothly it fit. I actually like the really simple design and I think the keyhole detail is a cute addition if you're looking for a little something extra. This has definitely earned a spot in my everyday rotation.

One-year update: My ThirdLove bra has held up well over time. The fabric is soft to the touch, even after multiple washes. This isn't my most-worn option, so that may have something to do with it, but, I wash it in the machine with the rest of my laundry and let it hang dry, so I think that's impressive.

ThirdLove's 24/7 Cotton T-Shirt Bra is soft to the touch, supportive, and comfortable enough for all-day wear. It's also true to size. The main standout for me was that, at 32E, the 24/7 bra's support system was successful without feeling restrictive or creating unflattering rolls under a T-shirt — both of which are my standard complaints. I was also impressed by the design — typically, when the bridge between the two cups isn't separate, it refuses to lay flat against my skin despite the cup sizes being correct. However, single-piece constructions also make for a smoother, better shape under T-shirts, and ThirdLove's version managed to do both — a smooth silhouette and a perfect fit.

It's also a bra you may forget you're wearing. The ultra-thin memory foam cups form nicely to the body, and the material is breathable enough to auto-regulate for the most part. In terms of looks, the keyhole detail in front also creates some interest to break up an otherwise basic bra. However, I did notice the band below the keyhole starting to crease if I slouched all day at work — which makes it look a little cheaper in my lingerie drawer.

One-year update: ThirdLove's 24/7 Cotton T-Shirt Bra is still comfortable one year later, and it's held up well after less-than-gentle laundry cycles (I admit I don't often spoil my delicates with a separate cycle). The band hasn't stretched, but it is still creased, and considering that it's the materials and fit I love most, I'll likely try the Cotton Plunge Bra ($68) next time.

I've loved nearly every ThirdLove bra I've tried, and the 24/7 Cotton T-Shirt Bra doesn't disappoint. It's so comfortable that I forgot I was wearing it, which is something I've only ever been able to say about ThirdLove's bras. The fit is absolutely perfect, so I don't need to constantly adjust falling straps or chafing underwire throughout the day. The new cotton fabric feels soft and natural against my skin and contrasts nicely with the more common lacy synthetic fabrics most bra makers use. True to its name, you can't see this bra under a T-shirt, thanks to its smooth, flat seams.
