No no no no no---
I can speak only for UT, and there not as an advisor or anything and only really from what I observe sorority girls wearing on campus here and my alumnae friends from Texas schools here in Austin. But no! no no no.
It's true that girls at UT and I'm sure at Tech too wear this look for football games and things like that but recruitment is different than those... Those are really ultra-casual and even first rounds is a different deal. I actually don't think that outfit is heinous but I wouldn't wear it for recruitment. Honestly I also agree that that dress is too summery for right now... I don't know if it's been as cold in Lubbock as it has been here but GIRL! don't freeze yourself!
Good luck with everything. I went up to Lubbock for Thanksgiving and got to see the Tech campus. It's so pretty!
