Are you, like me, are considering briefer style shapewear, want something that will not show a waist line, and usually wear a full figure bra?
This body suit style shapewear I came accross might be of interest. The Anita body briefer is a micro fiber, double layer, (like the afore mentioned plus size swimsuits, the miraclesuit), body briefer.
These come with built in, adjustable plus size bras. The full figure bras are underwire bras with an stronger underwire, wide straps and support panel in the cups. In sizes up to 44F!
And this style of shapewear fits like a second skin, which would be perfect under your tightest clothing! Like all your really comfy knits!
