Set the Table:I love my Pom Pom Bird Table Runner from Pier 1. Throw it over a vintage yellow table cloth for a table setting that screams Ole!
I am also loving this garland from Anthropologie's BHLDN, but I am sure there is a cheaper way to DIY.
Food & Drink:
Serve some fresh salsa (recipe here) and Margarita Punch (recipe here). I recently made some chicken enchiladas, but tacos are always a good Mexican staple. You can set up a Taco Bar with lots of different toppings.
Dress Like A Hostess:
Etsy has some great Mexican embroidered dresses, and I am loving this cobalt one from Crooked Tree Vintage.
Happy Cinco De Mayo!
