Three Floor 'After Hours' One-Shoulder Zip Accent Mini Dress

Era / Decade

Mid-2010s (circa 2014-2016). This was the peak era for Three Floor's structural, zip-heavy cocktail designs which were popular among fashion bloggers.

Material

Likely a blend of 95-98% Polyester and 2-5% Elastane/Spandex. Features a textured, heavy-weight bonded crepe or scuba-style fabric often used by the brand for architectural silhouettes.

Condition

Good. The garment maintains its structure, but there is visible wrinkling and potential slight discoloration near the underarm and neckline. The gold-tone hardware zipper appears functional but may have minor surface scratches from use.

Demand Level

Moderate. While the 'hyper-structural' trend of the mid-2010s has cooled, white cocktail dresses remain in demand for seasonal events, particularly 'white parties' and graduation ceremonies.

Resale Value

Estimated Resale Value

$45 - $85 USD (Low: $35, Mid: $60, High: $95)

Estimated Retail Value

$250 - $350 USD

Comparable Sales

Recent sales on Poshmark for Three Floor mini dresses range from $50 to $90 depending on complexity. Similar white one-shoulder models typically sell faster than more colorful versions.

Description

Stunning architectural mini dress by Three Floor in a crisp ivory/off-white. Features a dramatic one-shoulder neckline with a signature diagonal gold-tone exposed zipper detail. The skirt has a structural draped effect with a wrap-style hem. Perfect for cocktail parties, bridal events, or high-fashion evenings. Fully lined with a side or back zip closure.

Key Features

Architectural silhouette, signature gold-tone hardware, 'blog-famous' brand recognition, heavy high-quality fabric that holds shape, flattering draped skirt.

Authenticity Indicators

Distinctive Three Floor branded neck label (not visible but expected), branded zipper pulls (usually stamped with 'Three Floor'), and high-quality heavy fabric density and complex panel construction. Confidence: High.

Flaws to Note

Significant wrinkling (requires professional steaming), potential yellowing or deodorant marks in the underarm area of white fabric, possible minor fraying at the edges of the zipper tape.

Selling Guide

Where to Sell

Poshmark, Depop, and Vestiaire Collective are best for this 'fashion forward' aesthetic. The RealReal is an option if labels are pristine. eBay is good for a quick sale but may yield a lower price point.

Selling Tips

Steam this item thoroughly before photographing to show the architectural lines; it looks poor when wrinkled. Use keywords like 'Asymmetric', 'Structural', 'Cocktail', 'Avant Garde', and 'White Party'. Mention the size accurately as Three Floor often runs small (UK sizing conversion).
