I recommend Diptyque Eau de Toilette Oedo as a summer fragrance! The scent is light, and the longevity is pretty decent. To describe the scent, it smells a bit like mosquito repellent, but it has a strangely charming appeal and is on the lighter side, so I think it's perfect for summer. When I first smelled it, I wondered what it was, but the more I used it, the more appealing it became. I highly recommend it!
