Quick Question - Which collar heights work best here?
Both work. I think collar height is a bit like cuff length in terms of how much to show. Most people agree on 1/4" or 1/2" looking best, but it's personal preference. Both collars look very nice with that suit. I saw your posts in the SuSu thread, just pick whichever collar stays under your lapels the best. I like even larger collars, but I'm not sure about your build.
CaptainTohm / ericgereghty / wigglr for all the advice throughout the thread. Thanks, it looks like the president is .5"
