Holland Cooper sizing

[sunnydayys]

Hi,

Thinking of purchasing a Holland Cooper Camden longline coat and just a bit unsure about sizing.
Website says S/M is a 10 and M/L a 12.

I'm generally a 10 and do prefer slightly more fitted than looser but would you go for a Small or Medium?
Anyone got this coat?
How do you find the sizing?

Hi, can anybody confirm whether Holland Cooper clothing comes up small please? I'm a size 10,but their coat sizing states size S fits an 8-10 and size M fits 10-12. So I'm quite confused which size to go for 🥴.
Thank you.
