Great trousers. I bought these, size 170cm, for my daughter who is 5' 3" tall or 160cm and they fit her perfectly. These trousers come up a little small as I learnt from the previous pair that I bought her. But she loved them, so we purchased the next size up.
Bought one pair each for me and husband to wear for Tai chi lessons.
The waist size is quite small so i cannot wear them. His fit well he is small build.
Better if website listed more measurements (max waist and thigh diameter) rather than just height. If you are 170cm go a size up as they come up slightly short.
