Vintage 60s Blue Arnel Micro Pleated Tent Dress | Plus Size 3X/4X (57″ Bust) | Mod Ruffle Collar | AS-IS

Finding true plus-size vintage from the 1960s is like finding a unicorn—and this one is a beauty. Made from the era’s famous “Arnel” triacetate jersey, this dress features permanent micro-pleating (crystal pleats) that gives it a fantastic, swingy texture that stretches and moves with you.

The silhouette is a classic 60s “Tent” or “Trapeze” cut, hanging free from the shoulders with massive volume through the body. It features a high neck with a charming white ruffled collar. The vibrant royal blue color is deeply saturated and looks amazing in person.

Fit Note: This dress is essentially “Free Size” through the waist and hips due to the tent cut. It measures roughly 57 inches around the bust/body, making it a comfortable fit for modern Plus Sizes (2X, 3X, potentially 4X).
