I'm not too familiar with the differences in dress shirt collars; I was hoping someone could help me out a bit. I recently bought a white dress shirt by APC. I was planning on wearing it with my grey vneck sweater and with my black button cardigan. The problem I had was when I put it on it seemed like the collar was too stiff or too strong if that makes any sense. It stood up way too far. If I undid another button then it fell really far away and looked bad. It's hard to explain what I mean. I tried both sweaters on with another shirt of mine, this time with a floppy collar and it looked a lot better I thought. What kind of collars should I be looking at here?
