Thank you both. MsMaven, I was wondering if the 8 would be too big but I stuck with that size after your post. Suz, I hoped you would weigh in because I thought I once saw that style on you, loved it, and I think we have a similar build. If I found the right conversion table online, that would mean a UK 6 might fit me better. I'll have to wait and see, have ordered the 8 since the sale was about to end, and yes there's always free returns.
Sadly, no B&M carries Banana Republic here in Belgium.
