Wearing a black down coat will make you look thinner, because black is a visual "slimming color", which can offset the width of your body and make your body look slimmer. In addition, black has a shrinking effect, which makes the body more compact against the background of black. In contrast, white and blue down cotton-padded clothes have poor slimming effect. White will highlight the width and outline of the body and make it look fuller. Blue will make people look fresher and more natural, but it will not be particularly thin.

Down cotton-padded jacket refers to clothes filled with cotton, down and other materials to keep out the cold, which are divided into long and short ones.
