iim tryna buy a pink dolphin hoodie, ive never bought any of their stuff so i have no idea how it fits, ive seen the size chart but it didnt help either. im about 5'6 and 135 pounds, i like my hoodies big i think i would be a large but theres this one hoodie i really want and they only have a xl you guys think that would be way to big? and what u guys think size shirt i would be? in diamond im a M but its a bit small and a L is to big for me.
