Most Helpful Guy
It depends on your personality, for both dressing and flirting. I checked your "personality" here on GAG but you have "no comment" so it'll be tough to go off of since there are SO many personalities out there.
If you're chill and laid back, then just a pair of jeans that flatter your legs and butt with a top that's not showing too much (just enough to keep them guessing).
If you're more on the conservative side then you could do the same thing only dress it up more. Maybe a pair of dress pants or what not.
If you're the really closed off type then just wear something that doesn't show anything.
Again, it all depends on what you're like. It also depends on how cold it'll be. You wouldn't want to freeze your butt off in something skimpy now, would you?
