Peach is the like the red counterpart to the blue Arctic, which I'm really fond of, but also seems to not be a big seller.
My problem with the pastel colors is that they seem trendy, and I'm afraid they'll just look dated in 5 years. If we were at the $500/600 price point of yesteryear, I'd be more willing to do it, but It's hard to justify $900 for a pair these days unless I have some semblance that they'll be (mostly) timeless.
It's funny you say that. I had the same thought earlier, specifically, if the Zephyrin in peach go on sale at some point and hit the $600 USD mark, I'd pick them up. While I do think that the Peach color isn't trendy, (I think it has a really nice elegant and timeless look to them), I can't and won't do it for the current asking price.
JMM nailed the shade of pink though, and with the brown lenses. If anyone has dark brown hair and any sort of rosy hue to your skin complexity, these shades will look beautiful on you. You would look epic pulling up in a convertible to your hotel of choice on the Amalfi coast.
