I bought these bad boys on my trip to Gunwharf Quays the other week after lusting after them last year. They're leather, and just the right shade of acidic yellow to float my boat. I'm picturing these with all sorts of outfits this Summer to bring that neon factor.
Like I said, I saw this in store last year so if you're lucky you'll find a pair kicking about in an outlet store somewhere like I did. I always find I need to size down when buying from Carvela, so that's something to bear in mind if you're ordering online!
