Product Insights & Style Tips

The Theory Mock-Neck Cinched-Waist Peplum Sweater has a quiet, refined mood that feels instantly polished. It is a wool knit with a soft hand, pulled over for a clean, structured look. The mock turtleneck sits neatly at the throat, while dropped shoulders lend a calm ease. Long sleeves frame the arms, and the cinched waist leads to a peplum hem for subtle movement and shape.

Cut as a pullover, the piece slides on with no closures. The cinched waist creates a defined silhouette without cling, and the peplum hem adds lift through the hip. The relaxed ease at the shoulders contrasts with the waist-narrowing line, giving it versatility to layer over a base layer or under a coat. The model is 5'10 tall and wears a US size 4/Small, which offers a sense of the drape and proportion in real-world wear.

Theory speaks in clean lines and modernist polish, and this knit sits at the core of that language. It’s the kind of piece that teams with tailoring for a city-ready vibe or with more relaxed denim for weekend ease, a quiet luxury update to a wardrobe staple.
