Eau de Guerlain
This is the very definition of a light lemony scent and it's very refreshing. I adore it already and I've only had it for one day. It's more complex than it seems and the drydown is really lovely, it lingers more than you might think for something light. It's also a gorgeous bottle.
I had quite a splurge yesterday. I'll be back to report on my other purchases soon.
