I never buy expensive sunglasses because I'm guaranteed to loose or break them within a month. So I mostly stick to Forever21 and Target for my sunglasses needs; I never spend more than $10 on a pair.
Now, the fancy, colorful pair I'm wearing in the photo below is even better than my Target and F21 versions because they were free. I got them in a gift bag and I think they're meant to be a cheesy party favor, but I love them. To some they might seem dated and down-right ugly, but to me they have potential to look like a Proenza Schouler-inspired accessory.
Sunglass ?, Gap tank, McQueen for Target pants, Dolce Vita shoes from Eviva.
Still questioning the sunglasses? Well, let's just say the price was very recession-friendly.
