You never have a second chance to make a first impression. Cliché? Totally. True? Absolutely. It takes about seven seconds for someone to make a snap judgment of you, and they're mostly relying on visual cues.

Present a polished front at your job interview by keeping your makeup light. Think: BB cream, blush, neutral eye shadows, mascara and a swipe of lipstick. Depending on the kind of job you're interviewing for, you have some wiggle room with the color of your lipstick.

Figuring out what makeup to wear on a first date can be tricky. Since first dates are already awkward enough, stick to makeup looks you know you slay. You'll feel more confident, and you won't be worried about that new lipstick getting all over your teeth. As for date-night hair? Easy. Beachy waves or a sleek blowout are always winners.

Meeting your significant other's parents is nerve-wracking and exciting. One, you want them to like you. Two, it means taking a big step in your relationship. The last thing you want to be worrying about is your eyeliner running. For stay-in-place liner, choose a liquid or gel formula. Even out your skin tone with tinted moisturizer and concealer, and dab on a lip and cheek stain for a healthy glow.

And now is not the time to rely on dry shampoo. Wash and blow-out your hair, and be sure to set your style with a light misting of hairspray.

If you choose to do your own hair in makeup for your wedding, the most important thing to remember is: Don't do anything too trendy, and stick to makeup looks and hairstyles you've got down pat.

It's your party, and you can wear glittery eye shadow if you want to. This is the time to try out that new eye makeup tutorial you just watched on YouTube, or break out that red lipstick that's been neglected for far too long. The most important thing: Have fun with it.

Same goes for your hair. Take inspiration from models like Gigi Hadid and try a fierce slicked-back look or an effortlessly chic high ponytail.
