There are many causes for dark circles, and the pinch test can help you figure out what's causing yours: very gently pinch the skin under your eyes with 2 fingers. If the darkness disappears, then it's likely that it's being caused by the appearance of blood vessels under thin skin. If the darkness stays, it's more likely to be hyperpigmentation. When you know the cause, you can better treat the problem.
If you suffer from acne, dryness or redness around your mouth and chin, brush your teeth before you do your skincare routine because toothpaste residue can remain and irritate the skin.
Sleeveless tops, like simple shell tops, are comfortable and visually less bulky on the sleeves of the blazer. Choose a neckline that lies flat under the blazer, or rests comfortably above the collar.
A simple hair elastic can solve the problem! Attach the hair elastic around the button. Pull the elastic through the buttonhole, and then loop it around the button again. This will close your pants together while giving you more stretch to work with. Hide the elastic with a belt or under a shirt.
