Dress for "beach casual" wedding at 20 weeks

[kballerina]

DH and I will be going to his BFF's wedding in the beginning of September in Cancun (yahoo!!) when I am 20-21 weeks. The dress code for the wedding is beach casual - the groomsmen (all 2 of them) will be wearing linen pants and Hawaiian-type shirts with leather flip-flops. Anyway, I've been looking for a dress that isn't maternity so that I can wear it more than once or twice. I found this dress at athleta and love it, but am wondering if it's not "breezy" enough?
Thought I could jazz it up with some fun sandals colorful bangles, and a floral silk scarf? Of note, I'm 5'0" and 105 lbs - bigger, flowy dresses tend to overwhelm me in fabric, so I am trying to avoid looking like a kid playing dress-up. Opinions?

I think it is very cute. Wear some bright accessories and it would totally work plus that dress is totally easy to wear again
