Knit Cover-Up Mini Dress with Open Back and Side Ruching | Lumia

The Cover-Up That Goes Beyond the Beach

Style, stretch, and that open back detail everyone notices

This knit cover-up mini dress was made for the woman who wants to look effortlessly put together from the pool to the patio. The deep open back adds instant visual interest, while the scoop neckline in front keeps the look balanced and wearable.

The knit fabric — a soft blend with subtle lurex threading — catches the light in all the right ways. It moves with your body, stretches where it needs to, and dries quickly after a swim. No stiff, boxy cover-up energy here.

The adjustable side ruching is the detail that makes this dress work for every body. Pull the drawstrings to shorten the hem, add texture, or create a gathered silhouette. Leave them loose for a sleeker, more elongated look. Either way, it works.

• Deep open back with a rounded scoop cut that creates an effortless focal point
• Adjustable side ruching with drawstring ties that let you customize fit and length
• Lurex-threaded knit for a subtle shimmer that transitions from daytime to evening
• Stretchy, body-skimming fit that moves with you without feeling restrictive
• Quick-drying fabric that holds its shape even after water exposure
• Wide tank straps for comfortable, all-day wear

Knit That Actually Performs

Built for beach days, styled for everything after

The 92% polyester and 8% elastane knit construction gives this cover-up mini dress real structure with genuine stretch. It doesn't sag, doesn't cling uncomfortably, and bounces back after washing. The lurex yarn woven through the fabric adds dimension without making it feel costume-y or overdone.

Breathable enough for hot days, polished enough for resort dinners. Pack it flat in your carry-on and it arrives without a wrinkle.

• 92% polyester, 8% elastane for stretch that holds its shape
• Lurex threading adds a low-key shimmer without going full sequin
• Wrinkle-resistant and suitcase-friendly
• Breathable knit construction keeps you cool in warm weather
• Quick-dry performance — wear it straight from the pool

One Dress, Every Setting

From poolside to happy hour — the Knit Cover-Up Mini Dress that keeps up

Throw it on over your swimsuit for a morning by the pool. Swap to sandals and a tote for a beachside lunch. Add a heel and a gold chain for evening drinks at the resort bar. The knit cover-up mini dress moves through all of it without missing a beat.

The side ruching ties give you real versatility — adjust the gather higher on one side for an asymmetric look, or pull both to create an even, ruched hem. Small styling choices that make a real difference in how the dress reads.

• Beach and pool — the obvious choice for a stylish cover-up
• Resort and hotel common areas — polished enough to wear anywhere on property
• Beachside dining — pairs naturally with slides or wedges
• Evening casual — the lurex shimmer earns its place after dark
• Travel — packs small, does the work of multiple pieces
