Tops with build it bras

I have but I'm only a B cup and I'm OK with them.
I would not be too sure about more "endowed" ladies, they might find it tricky.

Useless unless you are below a C cup or you don't mind being squashed.

I am far from massive or "endowed" but when I tried one it was very uncomfortable and pushed my frontage into a monoboob. Not a good look. I have similar problems with swimming costumes.

They just look hideous.

I too have wasted money on these bra tops. Ridiculous unless you are very slim.
They don't stay in place, don't hold you firm.
And always young, slim models in advertisements.

I’m interested in getting one. I’ve lost a lot of weight recently and, as per usual the first place I lose it from is my boobs. When I’m in the house I don’t bother with a bra anyway ( and none of my bras no longer fit me) but would like to have some t shirts that don’t make me look totally bra’less.

Oh "built in"!
"Build it bras" sounded like something to do with Lego!

I don’t like them, they aren’t flattering, and I find them too hot, as because the material is stretchy it clings to your body all the way down, not just where a normal bra fits.

I'm with Casdon. I'm not hugely well-endowed, probably average. I find that in the winter, pull-on bras and crop-top styles with built-in support are fine, but in the warmer weather it's like wearing a mini thermal vest! Luckily I can go without any bras or crop tops without looking too awful (I think!) unless I am wearing a thin, transparent top or a clingy T-shirt.

I have some from MS. I think they came in a pack of 3. They are hot to wear, but maybe nicer in the winter. I also step into them and pull them up.
I find my usual underwired bras are very uncomfortable now across my rib cage for some reason. I often go braless if I am wearing a thicker material top. I am a 34 B/C so I can.
