Side Boning T-Shirt Bras

Formally known as a contour cup bra, it has seamless cups with a thin layer of foam for shape and modesty. 

When the description says "contour cups" you know the cups are seamless, molded, and have modesty foam. The cup shape is formed using various-sized breast molds which is why they can be seamless. These wired and wireless t-shirt bras are specifically designed to be invisible under form-fitting t-shirts, hence the name. This style is not to be confused with molded bras, which have cups that are shaped using a mold. 

HerRoom measures the foam thickness on all contour cup bras. This measurement is in our "Fitters Comments" section on each product page.

T-shirt bras, also known as contour bras, are your go-to undergarments for achieving a seamless look under your favorite shirts and blouses. Unlike designer lace bras, these bras are designed without any extra bulk or decoration, so you can comfortably wear your outfits without worrying about your bra showing through.

Whether you prefer padded t-shirt bras for modesty or want to amp up your curves with a push-up style, contour bras have got you covered. Explore our wide range of choices from top brands like Vanity Fair, Natori, Calvin Klein, Chantelle, and more.

When it comes to t-shirt brassieres, most of them feature underwires to provide extra support and lift for a beautifully rounded shape. There are also wire-free designs available, which allow you to enjoy the comfort and seamless look of a contour bra without any wires getting in the way.

Finding the right bra size across different brands does not need to be daunting. With our Universal Cup Sizing™ system, you can get the accurate size no matter what line, collection, or style of contour cup bra you choose.

Since these bras are so versatile, you should have at least three in rotation: one to wear, one in your dresser, and one to wash.

Your bra should encapsulate and support your breasts while also smoothing out your curves. It shouldn’t compress your breasts or make them spill out, nor should there be too much space inside the bra that it fails to provide the proper support.

A contour cup bra focuses on providing support while maintaining a seamless look under clothing. A sports bra, on the other hand, is a snug-fitting garment that reduces breast movement during intense physical activity.
