i've never tried on a pair of diors but if im roughly 5'7, 115 pounds, should i go for a 17.5 or 19cm fit? i want a really slim fit but just not homosexual tight as fuck.
to be honest if I were you and I didnt know which cut to get, I'd hold off buying them until you could try them both on to see which one you like more, especially when a pair runs 350$+. Reason being, I was in the same exact shoes as you and was about to order some 19cm online since that's what everyone raved about. I decided to hold off and went into the Dior store to try all three of the cuts and see for myself if the 19cm fit me best. Lucky I went in, the 19cm were too skinny for my taste even when I considered the fact that they would stretch over time. I decided on the 21cm which I don't regret a bit since I believe they fit me much better than the 19cm's did. And the 17cm's I tried on were way more tight than I expected.
17.5 would be best for you
