2 pairs at the moment, but I don't like either pair! My favorite pair--a pair I found on sale at ATL for under $15--broke a few months ago, and I haven't been able to find anything else like them. I bought another pair at ATL out of desperation, but they are too rectangular for my face, and I still haven't even removed the tags from them yet. Fortunately, they were on sale for cheap. I stay in the $12-$30 range with sunglasses because I know myself well enough to know I'll either lose them or break them.
I have a small, narrow, oval-shaped face, but a rather large nose, so as you can imagine, it's hard to find a pair that works with my features. The oversized Jackie O sunglasses just overwhelm my face, and I also have an aversion to those blingy sunglasses with garish logos, hardware or rhinestones. Ironically, right now I'm wearing an old pair of Fossil sunglasses that I found in a drawer that are studded with rhinestones, which is why I tossed them in a drawer to begin with. I'm in a place of desperation because I need something that will shield against the sun's glare when I'm driving!
