We used Tommy Bahama Official Site: Island Inspired Men's Clothing, Women's Clothing, Men's Shirts, Swimwear, & More. and Beach Wedding Attire: Drawstring Linen Pants, Cotton & Linen Shirts, Shorts, Skirts - Island Importer. I also see alot of the girls using Beach Wedding Attire | Guayabera, Guayabera Shirts, Havana Shirts, Mexican wedding shirts, Hawaiian I have not personally used that site but am considering ordering the dads shirts from there. They do custom shirts with embroidery on them if you'd like.
