As you said, you are plump, so you are not suitable for light color. Your hip-wrapped skirt is light, which will make your hips fatter. If you have an advantage in height, that's fine. If you exceed 165, you will look sexy. A tall lady with a plump figure wears a hip skirt with white high heels, which also looks good.

If you don't have a certain advantage in height, I suggest you choose dark or neutral colors. As you said, wearing a black coat is also good. Black has the visual effect of slimming and shaping, which is a good choice. Considering summer, you can choose a black chiffon sweater or a hollow sweater. Black bats can also make you slim down to some extent, at least covering your shoulders and arms.

And your shoes, plump girls choose this kind of thick heels is the right choice, but if it is white, it will not look so good. White is an expansive color. Choosing black shoes and wearing black stockings looks plump and sexy on the whole, which is not as good as you said. I wish you happiness and more and more beautiful.
