Hi guys! So, I just received my sports coat from Suit Supply, which also is my first sport coat ever. I'm just 18, so I have a long way to go. I know that I need to shorten my sleeves, but not how much. I am also not sure about the length, is the jacket too long? Is there anything else I need to fix, or should I return the jacket because it's too big? Thanks! Edit: My thighs look super skinny in these pictures, it may be the angle. I'm usually not that skinny (I think).
