As far as returning in pj's, if it is the pjs you don't like, perhaps try buying her some sexier ones that you have laying out for her in the bathroom when she is cleaning up. When she gets up to go clean up, say "honey, i bought you a little something that you can slip into, if you want to..." Then compliment her on it when she wears it into the room. I am not talking about little lingerie, but maybe a satiny cami set, or Victoria's top & short set or a little lace & satin gown. Maybe she is feeling funny about her body.
