Girls One-Piece Playsuit 2521 Simplicity Vintage Sewing Pattern

Simplicity 2521 is a vintage sewing pattern for a girl’s coordinated wardrobe featuring a one-piece playsuit, blouse, skirt, and sash. Each garment is designed with applied bands at the center front and a classic button-front closure, giving the set a polished yet playful look that reflects mid-century children’s fashion.

The sleeveless blouse features a wide, round neckline for comfort and ease of wear, while the full skirt is softly pleated to allow movement and a flattering silhouette. The sleeveless one-piece playsuit includes a convertible collar, making it suitable for both casual play and dressed-up occasions. A contrasting sash completes the ensemble and may be worn in a variety of ways for added versatility and style.

This pattern is designed for fabrics with even lengthwise grain or plain weaves. Suggested fabrics include cottons, polished cottons, seersucker, broadcloth, chambray, linen, rayons, sharkskin, blends, and leno weaves, with similar fabric recommendations for the sash. Simplicity 2521 is ideal for sewists who enjoy creating classic vintage children’s clothing with coordinated separates and timeless design details.
