Are Expensive Sunglasses Worth It?

Apparently not, says one Fashionista writer who remarks that her cheap-o H&M sunglasses offer full UV protection, whereas many of the designer brands you might drop a couple hundred on offer nothing in the way of protection. That’s something else to add to the list of expensive sunglasses caveats. Not to mention that sunglasses are among the most easily lost and broken items in your fashion arsenal. On the other hand, sunglasses can be seen as “power pieces,” and how awesome would it be to own a pair of boss vintage Dior sunnies? (Answer: very awesome.)

What about you—do you favor cheapies over pricier lenses? How much can you spend on sunglasses before the purchase becomes ridiculous? [Fashionista]
