Zara trousers - sizing?!

[stickybear]

Hi, I realise Zara sizing is an endless mystery, but hoping someone can help me with how their trouser and jeans sizing compares! If I take a 10 in Zara jeans (mom style if it makes a difference), what size would I be in tailored trousers? Any advice gratefully received

I’m a 10 in Zara jeans and have both S and M trousers. I’ve got three different styles in medium, one is perfect, one is a tiny bit big, the other was a bit big on the waist but perfect elsewhere so I sewed a couple of darts in. The size small trousers are a perfect fit.
I had another small pair from Vinted but they were too tight so I resold them.
Good luck!

thank you. They're wide leg trousers and the jeans I have are quite generous, so I think I might take a punt on the S...
