Most Helpful Girl
If you're shopping for someone else I'd stick with v-necks and polos to be safe.
These are never bad looks and are very versatile (can be styled up or down depending on their style)
for pants cargos and jeans are always good choices. For jeans Levi's are always a safe brand to go with.
But I'd seriously let them pick out what they like as far as less basic clothing goes. Most guys have a particular brand that they're interested in (such as Huf, Stussy, Levi, Maiden Noir, Supreme, or UNDFTD) that they're into and they usually just get clothes from that particular brand from what I've seen, but I know that gets expensive so I don't know what to say about that, but plain v-necks and polos are always pretty safe maybe get them a couple of button down shirts too.
