Perfect Pair



Our low back bodies are “full body” products, therefore your dress size and bra size should both be taken into account when fitting this product.

When fitting the body, adjust the multiway straps to suit the garment the body is being worn under. Step in and gather the garment as you would with a pair of tights, work your way up from the bottom and pull up. Adjust straps and poppers to fit comfortably. Lift and adjust breasts as you would when fitting a bra.
