Most Helpful Guy
I don't know names for styles so I'm just going to describe the look I like.
Low maintenance, casual, fun, active. Let me ask you this:
How would you dress, do your hair, and style yourself in general if a guy was taking you out someplace where you'll be having fun doing active things, like playing laser tag, and you didn't want your clothes, or your shoes, or your makeup to get in the way of your getting into the activity?
Obviously you wouldn't go all out in styling yourself since you'll be sweating, and you won't be wearing heels. You'll probably be wearing some form of sneaker instead. And you won't be going all out on your hair for the same reason as your makeup. You won't be wearing skirts/dresses.
Dress to fit into those guidelines while still looking as good as you can. That's the look I go for. Jeans and T-shirt and sneakers works great too. Can't go wrong with the pony tail.
