Cocosa is a members only fashion club that offers members insider access to online sample sales from top designer labels.

Now, everyone’s idea of budget is a bit different and nothing on the website could be described as frugal, but you’ll definitely find excellent value for money if you want to splurge on a few key pieces.

Vera Wang party dresses at 60% off? You had me at hello!

Here’s how it works:

Cocosa.com cherry-picks sought-after, premium designer clothes and accessories from past and present collections, and offers them to its members for up to 50% to 80% off. Each Cocosa sale is announced to members in advance by e-mail, is focused on one specific leading designer brand at a time and is offered online for 48 hours. Once members have made their purchase, Cocosa will deliver the item, beautifully packaged within two days of payment…it’s every fashionista’s new best friend.
