What a t-shirt bra is
Short answer: A t-shirt bra has a smooth, seamless cup that does not show through thin tops. The name refers to the fact that it can be worn under a close-fitting t-shirt.
A smooth cup
Without seams and lace on the outside there is nothing to show through the fabric.
Under thin tops
That is where the difference shows. A bra with seams draws clear lines under a close-fitting t-shirt. See bamboo t-shirt for women.
With or without underwire
The model exists both ways. Without underwire it is softer to wear all day. See bamboo bra without underwire.
Choosing the colour
Under a white t-shirt, nude is less visible than white. That surprises many people.
Seamless
A completely seamless model is the closest you get to invisible. See seamless bra without underwire.
Size
Measure under and across the bust. See the size guide.
Washing
Laundry bag at 40 degrees and air drying. See the washing guide.
