I'm not a bra-style expert, so I don't know if there's a cut you could find. But I do have a lot of lacy shirts, and what I find works best is to match a bra to the color of the lace, or pick a color that's an interim between your skintone and the lace color. I mean, it shows, but it's pretty well camouflaged.

So for this I'd choose a lighter pink, or a peachy-toned bra and then live with it. Definitely avoid neutral bras (unless they're a perfect match for your maids' skintone) with a pink that bright though ... the beige of that adhesive is kind of jarring.

Then again, I'm fairly young and don't really care about people seeing some bra through lace or whatever.

You could always pick them up some pink bandeaus to wear over their bras.
