I assume you mean Light Blue for Men? The woman's edition is not bad, but I think the men's is one of the worst fragrance releases in the last 10 years. Shrill, grating, and nauseating. Unfortunately it projects well and lasts forever.
Polo is fine, but pretty tired. Honestly it smells kinda dated to me, whatever that means. Just this impression I get from it. Like I should be wearing a rugby shirt from the 80's or something.
I get where you're going here - something casual and easy to wear for the summer months - but I honestly think there are better options.
Are you wanting an aquatic specifically, or just something for general summer wear?
