Cute and colorful!
I absolutely love this sun suit! Waterlust has been my go-to for sun suits for years, and I own many of the patterns. Nudibranch Nirvana is my fav! High quality images of a number of vibrant sea slugs, bright colors, well-fitting, comfortable, and all-around cute and practical. love!!

Comfortable, well fitting, and beautiful!
The nudibranch collection was my first purchase from Waterlust, and I'm hooked! I got the sunsuit in size M (I'm 5'4; 135 lb) and it fits fantastic. It is fairly easy to don and doff with the pull cord on the back. I do wish the cord was a little stretchier / more robust, but I'm careful when I zip up so it should be just fine. It feels just a tad tight in the neck when walking around, but perfect once I'm in the water snorkeling. I wear it with the black,/nudi tights for full sun protection. I love it so much I've now ordered it in black to wear with full nudi tights. The colors are stunning and vibrant so I can be easily seen on the surface by family or a boat spotter. The material feels a little thicker than some other brands I've tried, which I really appreciate. Highly recommend!
