Help me identify a pair of size 10 trousers from Tommy Hilfiger

[DamePastel]

I like these trousers for work

Heaven only knows what size I need. I did buy a pair once before and they were size 6 but these trousers are measured differently. 34, 36, 38, 40.

i know in france a size 38 is a size ten. some of their trousers are size 6, 8 etc. i get that system. Some of their trousers are waist inches, i get that system but these trousers start at 34, so they can't be done by inches of waist. In france I think a top that's 38 is size ten. Is that right.
