Well, 12dn94dst has said the things I was wondering whether I should say.

So I'll simply ask some questions.

Did you ever consider that perhaps the active sisters took the time to find in this woman the things you have not? Perhaps she's a great student, or very involved in service to the community. Have you even asked what her interests are? Or are you too busy judging?

Maybe she comes from a family without your apparent sense of style.

The things you mention are superficial. Nothing that couldn't be fixed by contacts and a fun night of sisterly makeovers. Not that she should have to change just to please you... but maybe she's never had the chance to develop her appearance.
