Similar to Cool Water Summer Fizz? I would say try Chanel Platinum Egoiste - it still has that slight freshness to it but it comes off smelling so much richer & classier. I'm not good at describing the notes but I think this could definitely be a winner. If you arn't afraid of spending a bit more, I'd also suggest Creed Green Irish Tweed - it gets alot of rap for being similar to Cool Water, but I prefer it by leaps and bounds. You can smell the quality in it, and is extremly good in both warm and cool weather.
Also welcome to Basenotes.
