If you're going somewhere for a special evening and won't be coming back (or you're spending increasing amounts of time over at a certain someone's house), having a kit of your own stuff is a good idea. Sure, your lovah is probably glad to share shampoo and body wash with you, but what about makeup and styling stuff? Sharing mascara, even with your significant other, is a big no-no. A small, elegant case like this Hanging Valet Cosmetic Bag ($28) is a space-conscious way to keep your stuff together; you can load your usual perfume into a purse spray like the Travel Fragrance Atomizer ($6); a Cherry Print Mini Flat Iron ($19) will get your hair work-ready; and a handy two-in-one cheek and lip color like Benefit Benetint Pocket Pal ($20) makes getting a polished glow super easy.
