What is a T-Shirt Bra?

Contrary to what its name suggests, a t-shirt bra isn’t meant to be worn only under t-shirts. While it really is the best option under t-shirts, this type of bra can also be worn under any shirt, top, blouse, and essentially whenever you don’t want bra lines to show.

And if you’re wearing a white top, it’s a good idea to wear a t-shirt bra whose color is as close as possible to your skin tone.

Apart from being invisible under clothes, a t-shirt bra provides great support. It’s also very comfortable, enough to wear it all day. In fact, it’s one of the most popular choices for an everyday option.

This type of bra generally isn’t the sexiest or the cutest. So, if you want to wear a hot (maybe a low cut) dress, the t-shirt bra might not be what you’re looking for. Instead, its appeal is in the smooth look it gives under fitted clothes.

You can find both padded and non-padded t-shirt bras, depending on your preferences. Also, padded bras can have very light, but also much thicker padding. T-shirt bras also differ in the material they’re made from. You can go with a soft microfibre bra, or a more rigid fabric.

A t-shirt bra is versatile, and can work with most breast types, such as athletic or pendulous breasts. It also gives you a round and more natural look.

Despite all of its advantages, a t-shirt bra may not be the ideal fit for everyone. For example, women with breasts fuller at the bottom than at the top may experience gaping with this type of bra.

If you’re experiencing gaping (and you’re actually wearing the right size), one of the reasons is that a t-shirt bra doesn’t suit you. In that case, you can opt for something like a balconette or a demi bra. With these types of bras, the cups come down much lower, so gaping is less likely to occur.

T-Shirt Bra vs Regular Bra

Since a t-shirt bra is very versatile, it can be both very similar or very different from a “regular” bra. For example, both t-shirt and regular bras can, but don’t have to have padding. Also, they may or may not have an underwire.

One thing that sets t-shirt bras apart is that it’s generally seamless. This is simply due to its main purpose, to smooth out any lines under your shirt. On the other hand, regular bras may have horizontal, vertical, or diagonal seams.


Bra lines shouldn’t stop you from wearing a thin or tight t-shirt. With a t-shirt bra, you can easily solve this issue. It’ll smooth out any visible lines under fitted clothes.
