The sizing guide is broken, resulting in unnecessary returns.I already had a pair of these trousers and the size label on them says 30X30 - very clear.On the Next site, they are described as 30S and 30R. When I clicked on the “size guide” link, it only showed 30 waist with 30 inside length,” so not very helpful as there are two inside leg options.I gambled on 30R and they were too long. I had to send back two pairs of 30R and buy 30S instead.You should just describe the trousers on the Next site the same way they are labelled. In this case 30X30, not 30S which never appears on the trousers.
