Silk Bra Is It A Bad Idea To Wear A Boned Bra Under A Silk Charmeuse Gown?

Is it a bad idea to wear a boned bra under a silk charmeuse gown? - silk bra

Hello, I'm looking for wear a bra with my dress, sewn in cups because they do not offer the support I need. My seamstress said a longline bra, but my dress is made of silk charmeuse. I think I'm a little bit about how it might concern. Ideas?

This is the dress
