go on their site and get the email for the head of sales (i believe his name is logan). tell him what suit you are interested in and tell him what size/color and ask what price is with shipping. he will tell you all you need to know and he will ship it to you. and yes, it does fit massive, i think avalaan small is L or XL, i forget, but if you are 6'3'' you def wont be disappointed, no matter what size you get.
