I bought these trousers as I ride pillion on my other halves R1 and I had been wearing his trousers which were far too big for me! I'm normally a size 8 in trousers and bought a 10 as the discrimination said go 1 size bigger they fit pretty much perfectly they were a little big on the waist but the velcro fastener helped to make them tighter. I was able to wear my leggings underneath too which is great! I found the calves are quite tight to initially zip up so if you have a bigger calve that may be an issue, although I'm also 5ft 11" and they were about 3 inches too short which could've also been why they were a little tight to zip the calves. The shortness to me isn't an issue as my boots cover up my ankles. I'm also really impressed with this company's communication they reply very quickly and give you all the advice you need before purchasing anything will definitely buy from this company again in the future!
