keep! they are fabulous!! One problem I alway have with metal frames & more specifically, the little nose pads is that if I push them up on top of my head, say when I go into a shop, when I try to pull them down to my face again they always, always ruin my hair & I end up looking like a slightly demented scarecrow.
I didnt read all the responses but... since you have the obsessions which are a thicker frame, I would go for the thinner frame (conspiration) just to mix it up a bit. Although I do have 2 pairs of thick framed glasses, its just my style but since you have both styles to choose from where as I only had 1 lol I would go different.
