it's a bit try-hard. does the store where you bought your jeans not hem them? DC4 here in Berlin offer that service for free.
How is that try hard?
I get jeans in size 33 and whatever length they come in as long as it is above 34". If they are 35 to 36" i don't need to cuff, if they are longer i cuff. I am actually trying less hard than anyone trying to figure ou the "correct" length.
I don't actually try at all...I i tried less i wouldn't be wearing any pants!
