I just bought my first pair of raw selvedge jeans. Unbranded Indigo Tapered sold by Urban Outfitters. Seriously confused about what to do now. Do I have to put them on and get in a tub full of water? Should I just start wearing them as they are? Do I have to machine wash them once first? It was a bitch to get them on. Will they get looser with time? I bought size 33 and they fit my thighs tight but I my waist loose. Also the rise is very high.
