You should own these, I think.
I have a thing for sunglasses. We know this. I also have a thing for glasses-glasses - I even went on a full-on mission to track down the glasses Ali Wong wears in her HBO special (it took ages. It was totally worth it).
The problem is that sometimes my thing for sunglasses and my thing for glasses are at odds, because from time to time I am both in the sun, and also in the mood to see. I've thought about picking up a pair of transitional lenses - you know, the ones that turn into sunglasses when you're outdoors? - but another thing I am is very picky, and I've never found a pair that I loved both as sunglasses and as glasses. They feel like separate style categories to me.
