If you were sane, which I imagine the majority you were, you watched Dick Clark's New Year's Rockin' Eve from a sheltered area with a champagne flute rather than out in the beyond freezing cold of Times Square with nothing but a slab of cement to your name. The glory of this is that you got a front seat to witness JLo's NYE performance in the middle of all this mayhem. We'll get to the hair and makeup in a moment, but first – the outfit. What's a New Year's Eve celebration without a sparkly catsuit? To JLo, it is simply unheard of. Though she was quite bare (and shiny) on the last night of 2009, it must be because her hair and makeup took too long for her to pick out the proper clothing. So let's take some dos and don'ts from her look so you aren't forced to leave the house in a flesh covered leotard.

DO experiment with caramel highlights: Especially with the colder months in full swing, try something a few shades darker than blonde for your highlights. If you're a brunette, caramel is a great hue to accentuate your hair without looking over processed. If you have blonde hair, try a sandy shade and stray away from bleached blonde locks until your tan returns. If you're looking for a DIY treatment for subtle highlights, try the reusable MagiCap Neon Highlighting Cap.

DON'T give yourself Sharpie eyes: We know JLo has to wear her makeup on stage a little heavier so that it shows for miles and miles, but for everyday wear this smoky eye is way too much. JLo is belting it out but her eyes are hidden behind gobs of black makeup, what I fondly refer to as, "Sharpie eyes," as it looks like you've circled both of your lids with a big, fat Sharpie marker. To prevent this from happening to you, choose cream-based shadows and eyeliners to prevent the color from skipping all over your lids. Prime your eyes with foundation that matches your skin tone, and sweep the cream shadow, something that contrasts with your eye color from your lash lines to just above your creases. Apply a pencil shade that compliments the eye shadow, like brown, black, or another muted shade to the rims of your eyes. Top it off with some mega mascara, like Benefit BADgal Lash Mascara and walk the streets Sharpie free.

DON'T forget to put pants on. This is self explanatory, yet some (cough cough JLo) need a gentle reminder.
