Unfortunately my entire outfit is no longer available. All three pieces are from the Winter Kate Fall 2012 collection. Which was discounted in 2013. But if you head over to eBay.com, you will be able to find some Winter Kate pieces. If you live in the US, Poshmark is also a great place to find new or second hand items.
Sunglasses- House of Harlow 1960
