Taylor Swift illustrates beautifully the risks of wearing blue eye shadow. "Although it can be done in a way that’s edgy (a deeper matte shade paired with winged black liner), it’s not easy to pull off without looking very 80s and dated," says beauty editor Bobbi Brown.
Celebs like Chrissy Teigen and Kim Kardashian understand the value of effective contouring - but it's important to get it right.
"Don’t contour with a dark powder. It ends up as two stripes on your face," warns Bobbi.
Blue eye shadow might be borderline but red is definitely out.
"It can be interesting on a runway model under certain lighting. But in natural light it can make you appear sick or hungover," says Bobbi.
"Don’t imitate the beige, flat, monochrome makeup that you see on the runways," advises Bobbi. "It will make you look washed out. If you want to try the nude makeup trend, remember that it involves gorgeous glowing skin and very soft hues."

Lining just the bottom lashline will instantly make eyes appear tired, warns Bobbi. "If you want to use liner, either only line the top all the way across, or both top and bottom."
Be careful when choosing your lip liner. "Don’t wear a dark lip liner over lighter lipstick. It’s too artificial and awkward," says Bobbi.
Keep your eyelid clear of eye cream, says Bobbi. "Your shadow and mascara will smear. Always make sure your lid is dry before applying makeup."
"It’s not necessary," declares Bobbi. "It shows, and will just get on your clothes. If you have the right foundation shade, you should just be able to blend it along your jawline. If your neck is lighter, a sweep of bronzer should even it all out."
