OT Style question

I had a question maybe some here could give answer to. My wife recently lost 24 Lbs. and her current clothing is getting a bit big. She has gotten out her "pre-pregnancy" jeans that are from 7 or 8 years ago. She fits into them really good again. She only has one problem. They are all flare jeans and she is worried that they are out of style now. I have been telling her they are still in, but she is unsure. Anyone have an opinion for her on this?
