Can I ask a question about bras in this forum? Is it considered okay to wear a coloured bra under a see-through top? Or would you say a black or neutral/skin colour would be better? What does anyone think about this?

Personally I would not wear a see-thru top without wearing a camisole or something over my bra. Anyway to answer your question I think you should bear in mind that any see-thru top is bound to draw attention to your bra. On the other hand if you keep the bra to the same colour scheme as the top then the contrast may not be that great and the bra might even look like it was meant to be part of the same outfit.

I don't think I'd ever wear a skin coloured bra under a see-through top as at a first glance I would look totally topless!
