I am a UK size 12-14, 5ft 4 inches and buying trousers is usually a nightmare. I was fully expecting for these not to fit but they do! I ordered the medium. The legs are loose without being baggy, the waist is comfy as elasticated and the leg length (always an issue for me) is good. I do not need to take them up! I also love the fact they are Blackwatch Tartan which is the vibe I have been trawling the internet for. It is surprisingly hard to find blackwatch trousers, so very happy.
