The Uniqlo PBJ are nice but too much taper IMO. After wearing them for a few months I don't like them anymore.
I like a 7" to 7.5" hem.
The PBJ is well below 7". Limits the footwear you can wear TBH. Dude who still boot tuck would like it I assume.
18cm or 19cm is pretty good. 8" hem is actually not bad either if you got a good break in the pants. All my dress pants are at least 8" and appear to be pretty slim still.
