Nothing screams, "I am vain," quite like someone who reeks of cologne or perfume (in fact, I prefer men fragrance-free). So where to spray and how to properly do it without fumigating everyone in the elevator? I like to spray perfume in the air and then walk into it. I also dab a bit on the back of my wrists, knees and neck.

You should never rub, because rubbing crushes the molecules of the fragrance and could ruin the scent. Some beauty editors only spritz the inner elbows and behind the knees because the fragrance stays a little moist and it turns out fragrance works best just a little bit humid.

Find out how to apply fragrance so it lasts longer in "How and Where to Apply Perfume So It Lasts Longer." I absolutely love the Coco Chanel quote.

Because it's the middle of February and we are all likely suffering the effects of wind-blown, scaly lips, I've decided to remind everyone of The Best Lip Exfoliating Tip of All Time, which I learned from a teen magazine in my youth and have been practicing ever since.

If you have scaly lips, simply lather on Vaseline, rub it in well, then take an old toothbrush and massage with the toothbrush the Vaseline into your lips in a circular motion. You'll find the toothbrush exfoliates, while the Vaseline moisturizes. Wipe mouth with a warm, damp washcloth and voila! No more scales! Repeat a couple times a day until lips are soft and smooth.

Try this and you will love me forever.

Extra tip: Everyone knows at least one Carmex user who is obviously addicted. But is lip balm really addictive? I answer that here.

No matter your face shape, no matter your body type, no matter your hair type, the most universally flattering hair length on anyone tends to be shoulder-length.

A shoulder-length cut works on all face shapes: it's not too long which can make a thin, angular face appear even longer and it's not too short, which can make a round face appear even rounder. This length also works well for all hair types: curly hair cut too short can appear pouf-fy and thin hair can fall flat if grown too long. As for ages, it works beautifully on women of all ages -- you won't be accused of trying to look like a college kid or worse, a Real Housewife of (insert California city here) if you adopt this length at age 50. If you are a college student, you won't look matronly in this cut.

I usually prefer waxing over shaving, but I don't love that growing in time that's required before you can wax your legs, so I usually end up shaving my legs. Too bad laser hair removal didn't work on me, because I was hoping the thousands of dollars I spent on it meant I'd never have to pick up a razor again. Wrong!

So in honor of shaving, I give you "Top 10 Shaving Tips."
