1. Shiny/ oily face
I probably hate this one the most because I am very prone to it. Oily skin can ruin the whole make-up, making you look sweaty and gross. There's a big difference between looking dewy and having a mirror instead of a face! Absolute no no!
2. Wrong foundation shade
A too light shade can make you look ill, a too dark shade old and dirty, a too orange shade... well, you know (Paris is guilty of wearing both too light and too dark shades; quite an accomplishment, I have to admit). The best color to put on top of your skin is exactly the color of your skin; sounds very simple, but as we all know is not simple at all. If you want to slightly alter the color of your skin for a specific look, at least don't forget to cover your ears, neck and decollete too!
3. Clumpy lashes
It goes without saying that it looks just plain wrong. I cringe away from mascaras that may cause that effect ( ekhm, Margaret Astor Air Max for example...) and I hardly ever apply more than one coat. If I want fuller, spectacular lashes, I just go for falsies; takes more time but is well worth the effort.
So, what are your top make-up pet peeves?
