The Sienna Women's Collared Button-Front Long-Sleeve Front-Slit Maxi Shirt Dress is your go-to choice for effortless, elevated style. Cut from a softly crinkled fabric with a structured point collar, a full button-front closure, and gently gathered ruching at the waist, this flowing maxi dress is perfect for women who want a look that feels polished yet easy to wear.

Why You'll Love It

  • Tailored Collar: A crisp point collar frames the neckline for a refined, structured finish.
  • Waist Ruching: Gathered detailing at the waist creates a flattering, figure-defining shape.
  • Front Slit Design: A thigh-high slit adds movement and a hint of leg with every step.

Perfect For

Layering with a wide-brim hat and boots for a western-inspired outfit, dressing up with statement jewelry for a night out, wearing to garden parties and warm-weather brunches, or pairing with a belt to accentuate your waist.

Care Instructions

  • Machine wash cold with like colors on a gentle cycle.
  • Do not bleach.
  • Hang to dry or tumble dry on low heat.
  • Iron on a low setting if needed, avoiding buttons.
