I'm really enjoying the men's input in this thread. It's funny AND constructive!
And I love the AWITY?
To the OP, I don't know Texas rush, but I'll go along with the advice that you shouldn't "change" yourself for rush anywhere. It's one thing to dress appropriately and adjust if that's what you normally do in similar circumstances, but if outside of rush you'd wear what you wear everywhere you go, then be true to yourself and see if you find a sisterhood that appreciates who you really are. Just be prepared in case that sisterhood isn't there.
