+1 on the curl you fingers with arms extended--most reliable method. Also, be very wary of sleeve length as most guys just leave them alone and most all need to be shortened. Best to wear a proper fitting shirt (correct sleeve length) to measure but can be done without by a tailor using a ruler. Finally, since you look pretty slim (or just have the skinniest legs possible) don't neglect taking the jacket in at the waist.
Agree with everything above. Especially comments by a tailor. Please don't wear those jeans with a SC. While you are clearly skinny you'd be far better served with a non-jegging option for your jeans. Either that or look for a sleeker shoe.
hey guys, thanks for the input. yeah, angle is bad (difficult when noone else around to take photo). appreciate input on jacket (and jeans) though! i wear the jeans (apc new standards) with tshirts but yeah probably too skinny for a SC.
