We were thinking about all the money a gal spends on make-up and grooming products. You know: the Sephora binge and shame jaunts; the Duane Reade/CVS/Walgreen hair accessory pick-me-up-basket-fill-ups; the Avon lady calling and you buying all she’s selling visits.

When it occurred to us the biggest error most of us make when applying make-up or styling our hair is that we do it facing a mirror.

Huh? What’s wrong with looking straight into the mirror? Nothing and everything.  While you get a fabulous full frontal view, you miss all the nuanced dimensions of how people really see you. (Well, not exactly metaphysically, more superficially and three-dimensionally.)

So, the one key grooming and beauty item you should have in your arsenal is a hand held mirror. It’s the biggest beauty buy of all ($2.99 and up) to make sure the back of your hair is in concert with the front, the clips are pinned straight, and the make-up is blended smoothly back from the jaw into the neck line.
