Jessica Alba Uses This 1 Beauty Product on Both Her Lips and Elbows

When it comes to surviving Fashion Week, both Rebecca and Jessica know the importance of packing the light but important things. Jessica, who is currently expecting her third child, told us that she keeps her Fashion Week purse stocked with hand sanitizer, lip gloss, and Tums (because upset stomachs happen to the best of us). Rebecca's first essential, however, isn't one that you can pack up in a purse. "Sleep is key" she told us, "followed by my favorite Honest Beauty Lip Crayon ($18) and charger tassle ($50) because my phone is always dying." We feel you, girl.
