basically the title...I was wondering what you guys think. I usually wear my sport coats and blazers without, never really got into it, but I see it very often online. For context, I like wearing blazers with shirts or polos, jeans or chinos, maybe with some nice shoes or just with sneakers when it's more casual. Do you think it's a must to have a few pockets squares too or it's more of an individual style thing?
