Thanks again for all the feedback! Sorry I'm not responding to each individual comment right now, as I'm checking quickly in between some tasks, but I read and appreciate each one.
I held off on expressing my feelings about it so as not to color your impressions, but I do like it MUCH better styled. Styling it, even as loosely as this, shows me that it's one of those things to throw over one of my usual casual day outfits, which typically consists of dark neutral jeans and tee or sweater. Those are most likely worn with black or metallic boots, and my black floppy beret/beanie will likely factor into those outfits too. The snake print guitar strap with a black bag would tie things together also. The Minkoff backpack that I'm wearing out would be fine with it as well.
Yesterday I was feeling like the color might be too *pastel* for me as well, until today I looked at it with the McQueen scarf -- that scarf ties together the color with black and the dark skull motif, taking some of the sweetness out of the color.
Just to cover all the bases, I had a look around at various online retailers because I don't want to jump on the first appealing puffer I find. However, it's apparently not easy to find a non-gearish, lightweight, mid-length puffer in a somewhat fashionable/flattering style and a pretty-for-me color. I did place an order for the Sam Edelman coat Angie linked to as well, out of curiosity, since I have wondered how a silver/pewter puffer would work for me. I think if it's not TOO shiny and I don't feel like a spaceman, it could be nice. So I'll hang onto this while I check out a couple more options.
