3.1 Phillip Lim T-Shirt Dress

This silk t-shirt dress by 3.1 Phillip Lim was recently worn by Eva Mendes and retails for $495, now marked down to $346.50 at Kirna Zabete.

Though it has a few differences, this t-shirt dress from Velvet at Shopbop is currently on sale for $75.60 and will give you a similar style for less.
