I love this vest. Seriously. It's probably one of my key fall pieces this year. Any chance i can wear this vest I do. I'm sure people around the office think I live in this thing. Not only is this vest good looking it also functions. Took it down to the desert for a late fall climbing trip and it kept me warm while I was resting between burns. It does like to collect dirt, chalk and dog hair but can be easily dry cleaned off. You can risk a washer but it is down so it needs a bit of extra special care. If you want to wear a thicker layer under I would suggest the recommended size however if you want more of a fitted look go a size down. I wear a small according to the size chart but got an XS instead and I'm so happy I did.
