I am a huge real housewives fan and I spotted a similar white blazer being worn by Kyle Richards at Yolanda's dinner party. Her's was originally from Zara (sold out) but this is a cheaper alternative.
Get the look:
Top: (sold out) similar (here)
Jacket: wetseal boucle blazer (here)
Shoes: (sold out) similar (here)
