I doubt that we have many or any in AB.
At the moment I am shortening a pair of Tu Trousers for my wife who is 5'5". The reason she bought long legged trews from Sainsburys is because they are colourful, lightweight and ideal to wear around the house and garden during the Summer months (If we get any more good weather.) However, it is the case that Tu Trews are made for somewhat very tall ladies.
I have telephoned Tu@Sainsburys and the chap I spoke to assured me that the trews could be ordered on-line in various sizes. He then endeavor to take me through the ordering process (which I well knew) and ended up by saying that it was all rather strange that Tu Trews appear to come in one size and are being modelled by young ladies of 5'11" and he would report the issue.
Seriously, I am not pulling your leg. Have a look for yourself and see if you would be able to order different sizes.
