High Waist Tummy Control Underwear | Slimming Shapewear Knickers

The Fashion Couture High Waist Tummy Control Knickers are a seamless slimming shapewear essential designed for women who want a smooth, defined silhouette under any outfit. With firm high-waist compression that covers and controls the tummy, these knickers deliver a flatter midsection and a more confident silhouette — invisibly, comfortably, and all day long.

Key Features

• High-waist design — sits above the navel to cover and control the full tummy area for a smooth, defined look
• Firm slimming compression — flattens the midsection without digging in or causing discomfort
• Seamless finish — no visible lines under dresses, trousers, skirts, or fitted clothing
• Breathable fabric — soft, moisture-wicking material that moves with you throughout the day
• Gentle hip and rear shaping — subtly shapes the hips and seat for a balanced, proportional silhouette
• Anti-roll waistband — stays flat and in place without folding or rolling during extended wear

Size & Fit

Available in a range of inclusive sizes. If you are between sizes, we recommend sizing up for a more comfortable fit. These knickers are designed to feel firm and supportive without restricting movement or breathing.

Care Instructions

Hand wash in cool water or machine wash on a delicate cycle. Do not tumble dry. Lay flat to dry to maintain the compression properties and shape of the fabric.
