Nicole Richie and friend Jessica Alba were just recently spotted vacationing in St. Bart's. While walking on the beach, Jessica wore a super cute Missoni kaftan cover-up..
I found some great alternatives to the Missoni ones which retail for over $400.
1) Badgley Mischka Ibiza Coverup $148 Saks
2) Charlie by MZ $195 BlueFly
3) Steve Madden $44
4) Ella Moss Caravan Tunic $145 Piperlime
