LEGGINGS AS PANTS
Leggings can look great with a long sweater or short dress and a pair of boots (over-the-knee or riding boots), but wearing leggings with a shirt that doesn't cover your backside is a no-no. Leggings are just not meant to be worn with short tops. It looks messy and unprofessional, and doesn't flatter
anyone, no matter how tall or thin she is. If you are going to wear leggings, pair them with a long-enough top.
OVER-ACCESSORIZING
Accessories have the power to dress up a casual outfit or jazz up something neutral, but overdoing it can have the opposite effect. Wearing too many extras can clutter up your ensemble, making you look like a Christmas tree. The key is to edit: Look in the mirror before you leave and take one thing off. Less is more.
TOO MANY PATTERNS
Like over-accessorizing, mixing the wrong patterns can make you look chaotic. Patterns go best with solids, especially if you're not sure which patterns can mingle. This spring, we are seeing patterns played against each other, but it's not a look everyone can master. To stay on the safe side, go bold on top and stay neutral on the bottom.
GOING TOO CASUAL
What you wear in your home is up to you, and comfort often trumps style when you're just sitting on the couch relaxing. When you go out, though, don't dress like you're lounging in bed. Even if you throw on skinny jeans and a slouchy sweater with riding boots to go get groceries, you'll look much more pulled together than if you stayed in yoga pants and a crop top.
