Sculpted, asymmetric and made to turn heads. The one shoulder long sleeve ruched thigh slit maxi dress bares one shoulder with a sleek diagonal neckline, while a single long sleeve and a detached-look cold-shoulder sleeve give the silhouette its striking asymmetry. Ruching through the bodice and waist hugs every curve, and the floor-length skirt opens into a daring thigh-high slit edged with a cascading ruffle — an evening dress built for parties, galas and the festive season.

Why You'll Love It

  • One-shoulder asymmetric neckline — the diagonal neckline shows off the collarbone and shoulder for an elegant, sculptural look.
  • Long sleeves with cold-shoulder detail — full-length sleeves add coverage for cooler evenings while the bare shoulder keeps it sexy.
  • Ruched bodycon fit — gathered ruching at the waist and side seam smooths and defines the figure.
  • Thigh-high slit with ruffle trim — the high slit flashes leg with every step, framed by a soft cascading ruffle.
  • Floor-length maxi — the long, body-skimming skirt gives a tall, statuesque line.
  • Soft stretch fabric — comfortable stretch knit moves with you so you can dance, sit and walk with ease.
  • Black or white — classic black for black-tie and Christmas parties, crisp white for birthday nights, engagement parties and New Year's Eve.

Fabric & Care

Made from soft, stretchy knit fabric with a smooth finish. Hand wash cold or machine wash cold inside out on a gentle cycle. Do not bleach or tumble dry. Hang or lay flat to dry and cool iron if needed.

How to Style

The asymmetric neckline is the focus, so pull your hair back and wear one bold earring on the bare-shoulder side. Strappy heels show off the slit, and a small clutch keeps the line clean. Who What Wear notes one-shoulder dresses lean toward the formal end of the spectrum yet are easy to style, and The Knot recommends a sleek bun as a black-tie-ready match for one-shoulder gowns. Three ways to wear it: (1) Black dress + strappy heels + sleek bun + statement earring for a gala or black-tie party; (2) White dress + metallic sandals + gold clutch for a birthday or New Year's Eve celebration; (3) Black dress + faux-fur coat or long tailored coat + pointed boots for a winter night out.

Does this one shoulder maxi dress run true to size?

Yes — it is a close-fitting bodycon style with stretch, so it runs true to size. If you are between sizes or prefer a less fitted feel, size up.

How high is the slit?

The slit rises to the upper thigh. It is designed to show leg as you walk while the ruffle trim softens the edge. Seamless or high-cut underwear gives the cleanest look.

Is the white version see-through?

The fabric is opaque, but as with any white dress we recommend seamless, skin-tone underwear for a smooth, invisible line.

Can I wear a bra with this dress?

The one-shoulder neckline leaves one shoulder bare, so a strapless or multiway bra works best, or adhesive cups for the cleanest finish.
