Uniqlo tend to be on the small side in the waist, while the length is about right: I tried some of their regular jeans on in That London before I went online for some selvedge denims, and when I tried on a pair of 32×34’s, I couldn’t get the bloody things above my thighs, and I’m no Olympic level cyclist! A pair of 34×34’s fitted perfectly, though.
Sadly the really heavy indigo selvedge Uniqlo leans with button fly are no longer made, but the lighter weight selvedge with zips are perfectly fine, almost identical to 501’s in most respects, and can be had in a variety of cuts, washed and unwashed.
I love them, the regular fit are excellent, none of that skinny hipster nonsense!
