When I was younger I used to think eau de toilette or eau de cologne was nothing but an inferior version of perfume. After all it's cheaper, has less oils and thus the scent lasts shorter. How wrong I was (the ignorance of youth!). Thankfully with age sometimes comes a little bit of wisdom, so now I know that eau de cologne is simply perfect for summer. When it's warmer and you want to wear light, airy scents anyway what's more fitting than an eau de cologne?
