Where’s the best place to find a T-shirt bra that really is undetectable under clothes?

I don’t have particularly big boobs so have always bought my bras from the high street, but I think I need something better. I’d like a bra that can be worn under t-shirts, ordinarily I end up with a ridge at the top of the cups and I want something that’s invisible. I know that the bra fitters at M&S aren’t highly rated, but I don’t know what my options are. Any ideas?

I'm a lot bigger than you and have struggled for ages, I like the gossard glosses, although they don't have any padding in.

I bought one recently but the top kind of rolls over and looks silly under a tight tshirt

My tshirt bras come from M&S. I don't bother with the fitters just try on what I think will fit plus size up down. No ridges and I'm an f

I've always had this problem!
Last month I decided enough was enough and bought two slightly padded bras ( not keen on tshirt bras as would hate nipples to be on show!) And bought in a size up so now the top of the bra is covering all my boobs....its worked....no more bulge.

OP try the boob or bust website to check your measurements- I did it following advice on here and it made a huge difference. I bought padded t-shirt bras from figleaves (own brand) and also wonder bra (just t shirt bras, not the huge padded things of the 90s ads!) and they sit really well under my clothes.

Sloggi zero feel bralette - I've got a few.
