Tip: Wait until the product is completely dry before getting dressed to avoid staining your clothes and remember to wash your hands well after applying.
1
Applying self-tanner the same day
The effect of self-tanners can last four to six days, so you should always test the product a week in advance to see if it’s the right colour for you. Running low on time? Avoid blunders by using a tinted product without self-tanning to moisturize your skin while giving it a nice instant tan. Best of all, it’s easy to remove with soap and water.

Trying false lashes for the first time
If you’ve never worn false lashes, you should try them out a few days ahead of time, to make sure they’re glued on properly and that you don’t lose them during the course of the evening. That’s not the look you’re going for! Read our Everything you need to know about false eyelashes article to learn how to apply them like a pro.

Tip: To ensure you’ve applied them properly and that they’re comfortable, wear them for a full day before the day of the event.

Doing your nails the day of the event
Nail pros will tell you: don’t wait till the last minute to give yourself a manicure. Ideally, do your nails the night before to avoid smudging and give them ample time to dry before your outing.

Tip: If you accidentally get some colour on your nail contour, use a nail contour crayon for precise, impeccable results.
4
Overdoing your makeup
Although you can wear more elaborate makeup at parties and special events, you should still follow certain rules. If you go for a smoky eye effect, then you should tone down your lips. But if you prefer the doe-eyed look, a bold shade of lipstick will match perfectly.
Also, restrain your use of glitter. For example, if you’re wearing anything sequined, avoid shimmering powder and sparkling oil on your face and body. Remember, moderation is the word!
Tip: Planning on wearing bright or dark lipstick? Don’t forget to use a lip liner to prevent the lipstick from bleeding or feathering.
