Can I look Attractive in Shapewear?

Hi Guys!

I am new at this forum. I am not much fat, but I don't look much attractive in simple dresses. In the last few months, I have lost much weight, but now, my skin is looking very loose. So, it is the right idea to put on any good shapewear under my clothes?

If yes, then, please suggest right large size shapewear from here

I am waiting for your responses. I want to impress someone special. I hope you understand.
