I hate shopping for lingerie of any kind. Finding things like the best sports bras or the best cotton underwear for women can be ridiculously difficult, mainly because there are a dizzying array of options. Even a quality, basic, essential t-shirt bra can prove elusive. The best of them are comfortable, supportive and as invisible as possible. Searching for one that is all of those things while also fitting well can take up a lot of time.

That’s why we did the work for you and put together this guide. Whether you’re looking for an option that comes in an array of skin tone-matching hues or want to invest in something luxe from one of the best lingerie brands, this guide has you covered.

What to consider when choosing a t-shirt bra

T-shirt bras aren’t just for wearing under t-shirts. They’re essential for any lightweight garment so you don’t get visible lumps, bumps, or gapping. When choosing one, consider the following.

Material

What the bra is made of matters. Smooth fabrics with some stretch, like jersey and stretch silk, work great, as do nylon, cotton, or modal blended with spandex or elastane. All of these mold over the cup shape without needing seams or darts, which creates a smooth appearance.

Lining

T-shirt bras often have a light lining which helps give it shape while also providing light support without the need for padding. They create a natural shape without the use of excessive manipulation.

Underwire

Whether or not you prefer underwire is a personal preference having to do with how much support you like. Most t-shirt bras have a flexible, floating underwire that moves with you, making it much less noticeable—however, if you’re sensitive to this, consider wireless bras.

How we chose the best t-shirt bras

We chose the best t-shirt bras by scouring online reviews and reddit threads. I also have a second career as a tailor, pattern maker, and wardrobe stylist for film, television, theater, and fashion with over 30 years of experience. I’ve seen a lot of bras in my day, as well as a lot of different breasts and have a pretty good handle on the ones that work the best for the largest number of people.

What is the difference between a regular bra and a t-shirt bra?

T-shirt bras are designed with molded cups, minimal seams, and less bulk to make them as inconspicuous as possible under thin knit materials like t-shirts and the like. Regular bras may have decorative lace or bows, as well as seams, all of which can create bumps and lumps under garments.

How should a t-shirt bra fit?

A properly fitting t-shirt bra should be comfortable while giving you a little lift and support. Ensure the front lays flat and your boobs are not spilling out of the cups.

Frequently asked questions (FAQs)

What makes a good t-shirt bra?

A good t-shirt bra is lightweight, simple, comfortable, and lightly supportive. You should be able to forget you’re even wearing it. Cups that mold around your shape are also ideal for a smooth, flattering fit.

What is the best t-shirt bra without wires?

The best t-shirt bras without wires are the ones on this list: the Anaona Trish Molded Cup Bra, the Commando Butter Comfy Curvy Bralette and the Wacoal How Perfect Wire Free T-Shirt Bra.

Can you wear a t-shirt bra every day?

Definitely. T-shirt bras are all I wear unless I’m dressing for a fancy event. Many of them, because they are seamless with light, molded cups, are more comfortable than other bras.

What t-shirt shape is flattering?

There are a few flattering t-shirt shapes, each with their own individual appeal. A slim cut will show your shape more, but a classic cut will provide a relaxed, drapey look. A high, crew neckline will broaden your shoulders if you have a pear shape and V-neck looks flattering on most body shapes because the V shape creates an elongated line.
