I prefer a bra with thicker fabric covering the breasts, but this bra has a thin feel. In cold weather I couldn't wear this alone under a t-shirt; I'd be revealing more than I like to! The back amply covers areas where 'spillage' occurs in thinly designed bras, but it constricts a bit behind my arms and is definitely too warm for summers in Texas. So in essence, the bra is too thin in the front and too bulky in the back.
