Most Helpful Girl
wardrobe depends on the occasion! suits are only for formal events silly you do not need to wear them to impress a girl...unless its for your job or something like if you work in a bank...
for school and every day basis, I love guys who dress simple...a nice tshirt or shirt and jeans, sneakers for shoes. hoodies are nice, or you can even wear simple dress shirts with jeans on certain days...like plaid or abercrombie looking ones...its really no big deal...i don't pay attention much to how guys dress as long as they look simple neat and tidy.
if you want some inspiration, definitely check out clothing sites like urbanoutfitters, forever21 men, h&m men, abercrombie, etc
for formal wear...GQ magazine can give you some tips you do not need to spend a lot of money just get inspiration from it for when you go shopping
