Never wear the one with the upper body separated from the lower body, otherwise the fat around the waist will be more prominent, and don't wear the one with a lot of fluffy flounces, which will make you look bloated unless you are thin. It's best to wear one-piece, simple lines that suit you, which can make your figure more neat. It is suggested to choose a darker color to achieve the effect of slimming, hehe. I hope it helps you.
