T-shirt bras are usually seamless or without raised seams, if any.
These bras offer a smooth silhouette over a body huging dress or a t-shirt.
They are completely invisible under a dress.
The padded cups conceal nipples and provides a smooth line under t-shirts.
They are designed for young girls who still need some training to wear bras!!
Young teenage or pre-teenage girls whose breasts are in their early stage of development and are small enough to accommodate into bras of standard bra sizes, can fit into these training bras.
They are of simple construction, stretch fabrics that do offer a little support or none, well the need also being none.
Some trainer bra styles may not feature cup sizes but mention circumference of the rib cage and back.
Trainer bra sizes range from AAA to A cups.
