These amazing last-minute lifesavers will help out even the most prepared holiday maven.

Emergen-C

Between crowded malls, holiday travel, and a demanding schedule, your body can feel run down very easily, which is why you need to make sure your immune system is happy. Emergen-C contains 1,000 mg of vitamin C and antioxidants to keep your health in tip-top shape, plus other essential nutrients, electrolytes, and B vitamins to keep you energized. Just add one easy-to-tote packet to 4 oz. of water and you're good to go. One of our staffers swears by the effervescent stuff, (Berry Blue is her fave) and shoves it in the hands of any sniffling or sneezing co-worker. Buy it at emergenc.com.

L'Oreal Paris Root Rescue

Some women can actually feel when their roots are growing in, like that type who screams out, "I need a touch up!" when there's one centimeter of natural hair color visible. But for women like us who are too busy to even tell, we only seem to notice how badly they've gotten conveniently right before an important event. And have you ever tried to book a colorist last-minute during the holiday season? It's nearly impossible. Enter Root Rescue, a precise permanent hair dye that you apply right to your hairline and wherever you need a touch up. Available in 12 hues guaranteed to match your hair color (both in-salon and at-home), the kit allows you to buy a few weeks on your dye job in just 10 minutes. Get it for $7.99 at drugstore.com.

Essential Cami

There's a fine line between classy and too much when it comes to cleavage, and camisoles seem to be your only option when trying to cover up. Thing is, camis can 1) feel restricting, 2) cause strap overload, 3) enhance your cleavage or flatten it down, or 4) create erroneous lines underneath your dress. Luckily, Essential Cami addresses all of these issues (and more). Simply put, it's a cover-up for your bra—only it's backless, and easily buttons in four places around the front. Did you hear that? It's your favorite V-neck wrap dress shuffling to the front of your closet, because with Essential Cami, it's finally appropriate for your office party.

Kushyfoot Flats To Go

We have a love-hate relationship with amazing evening shoes. On one hand, they're gorgeous in the store window and even more stunning when we try them on, but on the other hand they hurt like hell an hour into the party. And since the thought of walking around a venue barefoot and stepping on glass remnants from Uncle Joe's ninth goblet of wine is downright painful, we're extremely thankful this season for these foldable flats. Since they come with their own compact case, they slip easily into any evening bag (or your guy's pocket) so relief is always within reach. Treat your feet for $8.99 at kushyfoot.com.
