Inexpensive, light weight, non polarized sunglasses?

I know there is a ton of discussion out there, and some good points. But I cannot find a good brand to buy, and I have been reaching for a couple years now. I bought about 6 pairs of expensive sunglasses from well known brands, from eyeglasses stores - and none are comfortable or light weight enough.

What I am looking for:

• regular, women's sunglasses (ie. Not the super sporty wraparound kind)
• non polarized
• leoght weight
• good for a small head.

I had 3 Ray-Bans that I loved, but their frames have gotten much larger and heavier. I tend to drop my glasses a lot (I hang them from my Tshirt and they fall...) so I don't want to spend an exorbitant amount of money. I have a pair of polarized glasses and hate them, so looking for some non-polarozed options.

And of course they should have good UV protection.

Any brands I can try? If they have physical stores where they can be tried that's a plus.
