Limited-edition Barbour® Vaila quilted jacket

I'm having a hard time with sizing and wish J. Crew provided specific size charts with their 3rd party items. UK sizing is generally tricky and I ordered a size 8 thinking it was UK size. But it turns out it is a US size 8 which is a UK size 12. I'm in love with this jacket and definitely need a smaller size. It is so light and warm and I love the corduroy collar and sherpa-like attachment as well. It's beautifully made and hoping Jcrew will restock sizes.

Cheaply made, zipper does not work well. Received jacket with DARK BROWN detachable collar instead of WHITE. Would not recommend.
