To my nose Chanel allure sport Cologne sport smells of 'orange peel'.
I dont get too much lemon in it. For me the dominant note is 'Orange' and its really fresh. Very uplifting for that brief moment when you spray it.
Then ofcourse it fades into oblivion like most aquatics. I wish it lasted longer.
Light Blue for women is more 'lemony' (no oranges for me in there) and the longevity is far superior.
IMO they are different aquatic scents.
