Shoulders are difficult to alter. The tailor would have to open the back seam, take off the collar, shorten the collar, take in the suit at the back seam, re-attach the collar, and a bunch of other crap.My best advice to you, without any offense meant at all, is to sign up for the gym. In 6 months you'll be a size 36 and everything will fit you better. And you'll feel great. No one likes a bone-skinny dude even if he's dressed perfectly.
