Boho dress by Poppy Field the label.

This is the classic silk dress we've all been looking for. This luxurious slip, available in black, hugs the body in all the right places. This isn't because the slip is tight—but because the silk drapes so elegantly across the body. This bridal silk slip is flattering on all body types, and is a beautiful, feminine piece to wear on its own, or underneath a robe or another garment.

You can't go wrong with a classic.
