Anyone have a leather jacket from Brampton London?

[Bluecheese22]

I have my heart set on a leather jacket from Brampton London but the size guide on their website has nothing on it! I'm wanting to wear it with jumpers so wonder if I need to go up a size.

I was going to say I'd never heard of them, but Googled and I actually bought this jacket recently from Celtic & Co. I did notice when it arrived that it wasn't branded Celtic, but another company, turns out it was this one!

I am a 10-12 and bought a medium, which was fine, not tight, and could have taken a jumper under it.

I returned as it didn't suit me, but it was a nice enough jacket.

I was wondering why the Lilly jacket retails for £250 on their website, but only £109 via Amazon and £99 on eBay?
