Vintage-inspired elegance
Beautiful details and vintage-inspired style for those who love to dress feminine from the first layer to the last.




Bring authentic 1950s flair into your wardrobe with our black frilly petticoat from What Katie Did – the ultimate way to add volume, movement, and that signature retro swish to your favourite dresses. Inspired by classic mid-century underskirts, this vintage-style petticoat creates the perfect hourglass silhouette beneath your swing dresses and full circle skirts.
Crafted from lightweight, soft nylon that feels smooth against the skin, it drapes beautifully without adding heaviness. The generous frilly hem adds just the right amount of fullness, while the fabric moves gracefully and doesn’t cling to stockings. The elastic waistband ensures a comfortable and flexible fit for all-day wear.
Whether you’re dancing the night away or simply want to add a touch of volume to your everyday look, this black petticoat offers the perfect blend of vintage elegance and playful retro charm.
This lovely soft, lined petticoat provides beautiful fullness to your 1950s-style swing skirts and dresses. The skirt is cut in layers that stay slim around the waist and flare out towards the hem, creating fullness right around knee level – perfect for achieving that classic 1950s hourglass shape.
Wear it under your dress or skirt to enhance your silhouette, or let it bring extra swish and movement on the dance floor.
The elastic waistband is adjustable for a comfortable and flexible fit.
