I own the LouLou trousers in olive green. I’m 5’2 and had to hem them as they were too long. I ended up sizing down: 38 for my usual 38/40 (my hips are 41″ if that helps). The pic below shows the pants that are already hemmed.
Pro tip if you’re looking for a dupe: the khaki Essentiel Antwerp pants are similar to LouLou and they are better as they’re lined. Also they only have 2 vs 3 pleats at the top which is a bit more flattering for someone who has bigger butt.Sezane,6,$180,5’1-5’2 5’1-5’2,Bottoms,French Brands,Pants,Size 6 All Reviews,Pants,Sezane
