Here's a few tips to help you burst confidence in all of your outfits;
1)Embrace your figure
This is the first step not only in dressing you should know that you have to love yourself , not turning to a snob but accepting everything in you.
If you are a bit curvy you would want to wear tops that define your waist line, thinner stripes (thick stripes gives the illusion of a greater figure) , wear darker colors on the area you want to look slimmer with which means, if you have curvy hips then wear dark pants and there are dark colors other than black like brown, olive, burgundy and navy so just don't stick with black it's boring,and still you could wear bright pants but balance it with the other piece , one dark pieace and one bright piece.
As for skinny ladies , you should reverse the tips , wear bright colors , thick stripes and.. layers , layers will give the illusion of curves and also loose tops are yor best friend, as for pants boyfriend jeans and flared pants are the best.
2)Color combos
Colors effect one's mood and so everyone has his/her favorite colors ,so make your own color combo.
Some characters love a calm combo like white, nude and mint , others love a bright outfit such as cobalt blue and red.
3)Your style.
Never go out unless you love every piece you're wearing and you love your outfit, do not listen to what people say if you feel good then wear whatever you want and also don't be a fashion victim!
Wear a trendy piece that say a lot about you not just because you want to be fashionable , if you like it you'll look great in it and if you're wearing it just because it's a trend you'll look silly
