Yes, there are a couple I've noticed. English shirts seem to be cut a tighter slightly across the sides, they have shorter collar points on a "standard" collar than American collars and most importantly, they only use one sleeve length, the extended length, so you have to order the correct length or your shirt will be too short on the sleeve.
Guys don't talk about clothing, and then they look like scrubs.
Generally though, yeah threads about boobs and silken covering for boobs will attract guys' attention, be they sharp dressed or not. Of course, if you are sharply dressed you stand a better chance than a Sears catalog wearing scrub.
Lacks is cool like that.
I just lurk and like.
