Womens Cut Out Slinky Long Sleeve Mini Dress - Black - 14 - Peek-a-boo. This dress comes in soft and slinky jersey fabric and features a figure-hugging bodycon silhouette, mini length, long sleeves (which we think balances out the mini style perfectly), mock-neckline at front and back, pull-on design, and under-bust cut out detail. For the plans that call for a real showstopper, here she is. Style with heeled boots and an oversized trench coat for those day-to-night hangs. Evening only? Rock with strappy lace up heels and a rad red lip. Style: Slinky Long Sleeve Dress Fit: Fitted Length: Mini Occasion: Day to Night Design: Plain Fabric: 95% Polyester, 5% Elastane.
