cologne
Cologne gives you a light, fresh airy scent for a couple of hours. Cologne has the lowest concentration of the actual scent. Parfum as the highest. That is why parfum lasts the longest.. the entire night if you'd like and parfum is the strongest.
While parfum can be overwhelming if you use too much, with cologne, you can splash it on as liberally as you would like. Cologne is much cheaper too.
