Portable roll-on perfumes are the ultimate gym bag and purse must-have for us. Our latest love: Diptyque Eau Rose Eau de Toilette Roll-On. The chic, iconic French fragrance house has tinged the classic rose with a dash of tart blackcurrant and warm honey and cedar base notes. Just a dab goes a long way and really lasts— as does the generously-sized (gorgeously-adorned!) rollerball itself.
