UPDATE: Well now the sun is out and it's mellting the snow. It's 37 degrees according to our deck thermometer. A walk around the 'hood wearing just jeans and a cotton sweatshirt underneath the Burberry at full length was perfectly cozy. In fact, I got a bit hot and had to unbutton it. It's close fitting and pretty dense. So my guess is it should be okay down to mid-20s with proper underlayers. There's no wind today, though.

I was planning to ship the coat down to Rae (to have more room in my luggage) and try it on for everyone in CA - that way I can either return it or wear it home.

However, today's snow provides the perfect chance to test-drive the warmth factor.. Would it be totally wrong to wear it for a walk around the hood without cutting the tags, to see if it is indeed warm enough (it's 38 degrees out right now)?

Please be honest. On the one hand, this is an EXPENSIVE coat and I need to make sure it's practical. On the other hand, I don't want to do anything morally questionable.

Yay: Take it out for a spin.
Nay: Don't be a jerk.
