The Vespara Wide Sleeve Maxi Smock Dress by Boteh. 

Effortlessly elegant, this maxi smock dress features a flattering drop waist and dramatic wide raglan sleeves that make a statement. The charming pussy-bow neckline and button front add vintage-inspired detail, while an elastic belt with an antique metal clasp cinches the silhouette. Crafted from luxurious cotton voile blended with shimmering lurex jacquard, it's a piece that transitions seamlessly from day to evening.

GOTS globally recognised textile production certification not only limits the use of toxic bleaches, dyes and other chemical inputs during the production process of textiles, it also goes far beyond verifying the organic farming process to include every step of manufacturing.
