I'm really interested in this Arden B coat on eBay. It's NWT, and it's a size large. I asked the seller about the measurements and she said the chest measures 36 inches. Since when is 36 inches a size large?! Does Arden B sizing run really small? I looked at their online size chart, and it says a large is normally a 38-39, which would be perfect for me. I'm wondering if the seller measured wrong or soemthing.
