@RubyRae Was it that you could speed up the sleeves naturally folding if you just spray some water around the area of the forearm where the creases appear? I think I followed someone's advice on that and it worked well for my Self Edge CPO. I have long arms so the sleeve length doesn't bother me that much. But even as 190cm (6'2-6'3) tall the overall length of the shirt can sometimes be too long for my taste with some IH shirts. I think I nailed my fit with XXXL there luckily. SP-Large got room for my shoulders and chest but often found when trying different denim shirts from IH that then you get too much length with the SP-Large...
But yeah everyone just needs to find the perfect measurements that fit them right.
