1970's Orange Knit Dress by Picardo Knits.
We love this relaxed silhouette and the pop of color! Our model said it was really comfortable on and breezy because of the eyelet knit pattern.
The flattering fit features a drop waist and shoulders, balloon sleeves and matching mock collar and cuffs. The staggered eyelet knit pattern in the sleeves and skirt was a brilliant choice because it makes it a much cooler piece than it looks.
Made from a synthetic yarn that feels a bit sturdy but that choice is by design..she's made to maintain her silhouette drape a certain way. This is not a soft dress, but it feels great on. 
Shoulder (dropped) 15", bust 36", sleeve 26" to collar, waist 30", hips 38", length 38".
Mock neck 14", cuffs 6". Zips up back.
