I am thinking Paradiso with the O as a sun. Underneath, a woman in a bathtub, but on the sand with a coconut palm tree hanging overhead. She has her arm and leg half out the tub, with maybe the other leg pointed in the air. There's a lot of creative potential with this idea of a "woman bathing in Paradise." 

PLEASE NOTE:  
-The brand should be generally "tropically themed" in name and style
-Beauty in SIMPLICITY will be rewarded
-The O as a Sun is a requirement
-The lady in the bathtub should emphasize subtlety, relaxation, comfort, and enjoyment. No suggestive content allowed, and really only the head/legs/arms need to visible I imagine. 
-I'm open to other suggestions so please feel free to contact.
