And ofc, you'll wanna avoid thicker or textured fabrics that'll show under your clothes. As Sullivan points out, "A bra may be great at first but lose support or comfort after a little wear." Cotton and microfiber bras are best for everyday wear, while nylon and spandex are also great options if you're looking for something stretchy but super-durable. You get what you pay for, and while high-quality bras can be pretty $$$, they're well worth the investment. "You shouldn't see the neckline cutting into you or notice anything but a nice shape," Sullivan adds. "It should provide you the right support, coverage, and be comfortable all day long." Gaping cups, slipping straps, and too-tight bands will all prevent your bra from looking totally seamless under your shirt-not to mention that an ill-fitting bra is gonna feel *super* uncomfortable. "Above all else, I think a great T-Shirt bra, like all bras, should fit you properly," Sullivan explains. Though it may seem obvious, finding the right fitting bra is especially important when it comes to T-shirt bras. Also, it can have a wire or be wireless." And when you're on the hunt for the perfect T-shirt bra, here are few things to keep in mind.

"Traditionally, the coverage would be on the fuller side but there are different types out there now from balconette, to demi, to full. "A T-shirt bra is usually a lightly padded/lined bra that has a smooth cup with no trims or seams," says LIVELY creative director Sarah Sullivan. Not sure what qualifies as a T-shirt bra? As the name implies, it's pretty much any bra that looks smooth and seamless under a tee.
