We're busy people. Between our office lives, social calendars and the Bumble dates we squeeze in, it's a wonder we have time to feed ourselves, let alone spend time on our makeup.

And because we're always running from point A to point B with little time or planning, a last-minute invite from your BFF can instantly throw you into a frenzy! You know you've been there: Frantically applying makeup, and changing your shoes and hair in the office bathroom like Clark Kent. Well, Superman's got nothing on a lady with some handy beauty tricks up her sleeve that can take her from SFW to NSFW.

Next time your bestie calls at 7 p.m. saying she's got extra concert tickets, this is your game plan:

Upgrade Your Lipstick

If you're really crunched on time and have less than five minutes to spare, we suggest the ol' lipstick switcharoo. Turn that nude or light-pink glossy lip into something dark and bold by following this vamp lipstick tutorial. Trust us, this foolproof trick never fails.

Contour Those Cheekbones

Dramatic, chiseled cheekbones is a quick and easy way to transition your look from day to night. Stash a two-in-one contour-highlighting kit or le duo stick in your desk drawer and work your shadows before heading out for night on the town! This contouring tutorial is easy enough to do in your car or office bathroom.

Just Add Liner ...

Sometimes-especially when you're fighting the clock-a little eyeliner can make all the difference in upgrading your daytime look. Just swipe on a bold cat eye, or channel your inner '70s "Mod" with this graphic eyeliner tutorial.

... Or Smoke It Out

If you're already rocking winged liner, you've got the makings of a quick and dirty smoky eye on your hands, er, face.

Smudge out your liner with a kohl pencil like the Maybelline Eye Studio Master Kajal Eyeliner for serious smolder. Make sure to work some along the lower lash line, too. And, if you only have black liner to work with, swipe some along the upper and lower lash line and smudge it out with your finger.

Load on the Highlighter

Nothing says nighttime like some serious strobing. Stash an illuminating stick in your office desk or in your car in case of emergencies-because not having highlighter on hand is SO an emergency.
