Sunglass Satisfaction.

last night as i was going through the hubby and i's online check-in for our cruise in february, i was thinking about sunglasses. currently, i am in need of a new pair and wouldn't you know i'm going to need some when we're in the caribbean in 40 days! :) my only dilemma is that i can't decide whether or not i should invest in a more expensive pair or go for the less expensive side of things. i tend to scratch and lose my sunglasses, but i'm kind of in love with coach sunglasses! here's a few higher end and lower end in price of sunglasses that i found to be cute and possible options to wear while on our cruise :)

so what are you opinions? so i go with the more higher end designer sunglasses or go for the cheap-os? what type of sunglasses do you prefer? :)
