Bikini Shot of the Day: Katie Cassidy

Later in the day, Cassidy took to Instagram and posted several shots from her relaxing getaway, both on the beach and poolside.

For Cassidy, the trip is long overdue, and one that she actually told E! News about when we caught up with her in New York City last month.

"I haven't had a vacation in far too long," she said at the time. "My girlfriends and I are going to Miami once I've wrapped season two of Arrow."

We're glad to see the trip has finally come to fruition!
