Quick question re proper dress shirt sleeve length: in the past I've mostly bought 35" sleeves on my dress shirts, but I was getting fitted for a suit at Brooks Brothers last week and the sales person has me questioning if that is right, as he measured me and was sure I was a 35.5" or 36". Is there a set guideline for where the sleeve supposed to hit on the wrist/hand? The 36" that I bought feels a little long (obviously, since it's in comparison to the ones I have). When unbottoned, the cuff hits about an inch above the thumb/finger V. When buttoned, there is a bit of extra slack in the sleeves that I'm not used to. Is that how it's actually supposed to look? I've always been under the impression that you want the sleeve to hit just past the palm, but that could be b/c I mostly have OTR dress shirts w/ cuffs that are too large and don't keep the cuff from falling over my hand... Thanks in advance for the help!
