Has anyone got the Trespass Ladna coat? What's the sizing like?

[Worried123456]

I'm a 12/14 and was wondering if the medium would be ok? Do they come up roomy or do I need to get a large!?

Thank yoy if you can help!

I've got a trespass coat - not the one you mentioned though - I'm generally a 12 top/14 bottom but got the large size. Could maybe have got away with a medium at the top but felt more comfortable having the large around my hips. Also gives plenty of room for layers underneath if needed.
