You must wear fitted, tailored clothes: pencil dress is your best friend, but anything that focuses on your waist can be good on you. A-line or skater dresses are also welcome.
Fitted tops are very good choice, select stylish pieces especially in case of simple ones.
Depending on the size of your bust, V neck cut is the most ideal form for you, but boat neck can also be OK if it keeps you in balance.
When you choose a jacket, please consider your waist: a tailored blazer or you can put a large belt on the coat. Use design accessories, even belt bag would make your look more stylish.
