What do I wear under a backless knit dress?

A backless or adhesive bra, or a slip if the knit is thin. A bodysuit with a low back also works and keeps the line clean.

How should I care for the knit?

Knit designer dresses are usually dry-clean only. Fold rather than hang to avoid stretching, and watch for snags on jewelry and bag hardware.

Does it run true to size?

Knit gives some stretch, but backless cuts fit closely at the bust and waist. Check the size chart and consider sizing up if you are between sizes.

Is this dress worth buying?

If you want a Saint Laurent evening piece with an open back, the knit and cut are the draw. Compare it with other backless designer dresses on fabric weight and lining before deciding.

How does it compare with other Saint Laurent dresses?

Saint Laurent's other evening dresses tend to use woven or draped fabrics with more structure. This one is softer and more body-conscious, and the open back is its defining feature.

The dress itself. Backless designs usually ship without a slip or undergarment, so plan to supply your own.

About the Saint Laurent Women's Backless Knit Dress

A women's knit dress from Saint Laurent with an open back, cut for evening wear and layering over a slip or bodysuit. It is a designer piece, so its value comes from the label and the distinctive backless cut rather than the fabric. Rivals from other luxury houses offer similar knit evening dresses, but few combine an open back with a body-skimming knit this directly.
