So I've decided that I wanna get these jeans but unsure of what size I should get. I went over to the denim store the other day to try them on. I asked for a 29 but they only had 30 left and it was kinda surprised that it was loose. I think I could fit into a 28 nicely. So I was wondering if I should get a size 27 or 28? My waist is 78.5cm/31inch and I want my jeans to be pretty tight. Thanks guys! Any help would be appreciated!
