What Our Customers Are Saying


What is the purpose of wearing an unlined bra?

An unlined bra is a great alternative to a contour cup bra. Folks looking for fewer layers (and more breathability,) a more natural shape, and anyone who “doesn’t need extra help” (i.e., they don’t want added size from foam) may be the biggest unlined bra fans.

What is the difference between wireless and unlined bras?

The wire and lining are separate bra parts, so you can have both! If you prefer an unlined T-shirt bra with underwire, the 24/7® Classic Second Skin Unlined is a top choice. If you prefer an unlined everyday bra without a wire, the 24/7® Classic Unlined Wireless Minimizer is a surprise favorite. 

When is it best to wear an unlined bra?

They’re not just a warm-weather friend. Unlined bras come in many forms to serve different purposes. We offer everyday unlined T-shirt bra styles, minimizers, and more.

What breast shape is best for unlined bras?

ThirdLove bras will work for most if not all breast shapes. Asymmetric, athletic, round, side-set, and slender breast shapes may work especially well with the 24/7® Classic Second Skin Unlined Bra.

How much padding is in the 24/7® Second Skin Unlined Bra?

The beauty of unlined bras is that they are padding-free. No added bulk, no extra, hot layers. There are no foam cups in the 24/7® Classic Second Skin Unlined Bra, letting your natural shape shine.

How do I find the right unlined bra size?

Our Fitting Room Quiz can tell you in less than 2 minutes, which we especially recommend if you normally wear heavily padded bras and are looking to try unlined for the first time. If you already know your size in a different ThirdLove bra, that is also your unlined bra size.
