Some tips to feeling confident include...
1. Where an outfit that fits your body type- If your outfit doesn't fit your body type then it is unlikely that you will feel the way you should feel in an outfit.
2. Dress to impress yourself- dress in a way that if you look in the mirror you will look in the mirror and think "wow... I look good today."
3. Where something you feel is comfortable- if you don;t feel comfy and that you can do anything in the outfit you're wearing, then it isn't the outfit for you.
Those are just a few tips that I have. I will write more later on. Hope you can use these tips to help be the you who you're meant to be this new year. I love you all and Happy Holidays!
