Before you put on those earrings for Christmas, read this:
If you have a round face shape avoid hoops, and round earrings, instead go for dangles or angular pieces.
If you have a square face opt out of angular earrings and instead go for cicles or hoops or something not too angular, also go for drop earrings, without many angles.
If you have a long regtangular face avoid wearing long earrings, go for shorter wider earrings. full earrings that are wide.
If you have a heart shaped face earrings look really good on you. Go for full earrings that will widen your jaw line and keep it in propotion with your forehead.
If you have a diamond shaped face, which is rare, but it's out there, you'll want to wear earrings that are dangles, and studs. avoid ones with too much width, or you give yourself a square face shape, unless that's what you're going for.
If you have an Oval face shape you can wear it all! but keep in mind if you have a short neck to keep your earrings to the chin or higher.
