All Vanson DRs have that "collar gap." It's just the way they make DRs, not a "patterning error." You either care or you don't. Personally I don't mind it.Either way, seems a little bit shitty to make a snide remark about one of the premier leather jacket makers in the USA (used by people who... you know... actually ride) being unable to make a proper fitting jacket.
The appeal is that it is a ruggedly masculine heritage piece. Also most men look good in navy. If your style leans toward the rugged or workwear aesthetic then its a great wardrobe staple.I'm not sure it would look good with a croptop so YMMV.
Yeah I sized too long for my tastes based on Drew's suggestions/method as well. But Drew more or less intends for TOJ riders and motos to fit longer than other brands''. What you personally think about others' fits and where they "should" end is irrelevant. Use Drew's sizing method and then deduce how long you'll want it to be from there.
