Review via - 28th Nov, 2019 Ordered online (online only) and tried on in-store. Checked the size guide for the trousers which indicated Medium (33-35" waist), I am a 33" to 34" normally, and I wear 33" waist Levi's (501). However, when I tried the trousers on, they were too tight even though somewhat stretchy. It would seem for these trousers I would require the Large (36" to 38"). They are very nice trousers though, just need to be aware that compared to the size guide, they came up too tight around the waist for me. Also, the colour looks slightly darker grey than they appeared in the picture.
