How to Sew & Style for the Rectangle Body Shape

Create curves and definition with the right sewing patterns, fabrics, and styling choices.

Understanding the Rectangle Body Shape

The rectangle (also called athletic or straight) body shape features balanced shoulders, waist, and hips with little natural waist definition. While this body type is well-proportioned, the key to flattering it is creating the illusion of curves and emphasizing shape through strategic sewing and styling.

Sewing for the Rectangle Shape

Best Sewing Patterns

Peplum Tops & Dresses – add volume at the waist for instant curves.

Wrap Dresses & Tops – create diagonal lines that cinch at the waist.

High-Waisted Skirts & Pants – elongate the legs and emphasize the midsection.

Princess-Seamed Dresses – add feminine shaping down the torso.

Tiered or Flared Skirts – add fullness to balance a straight frame.

Fabrics That Flatter

Soft, drapey knits and wovens highlight natural movement.

Structured fabrics (like twill or poplin) help create shape in fitted designs.

Avoid stiff, boxy fabrics that hide your figure instead of defining it.

Sewing Details to Include

Waistbands and belts to carve definition at the middle.

Darts, pleats, and gathers to add dimension.

Ruffles or flounces at shoulders or hips to balance proportions.

Color-blocking or panels to visually shape the body.

Styling the Rectangle Shape

Tops & Layers

Wear belts over cardigans, tunics, or dresses to instantly cinch the waist.

Choose V-necklines or scooped necklines to soften straight lines.

Cropped jackets or blazers add structure and create a waistline.

Bottoms

A-line skirts and wide-leg pants balance the body with shape.

Skinny jeans or slim trousers work well when paired with a top that adds volume.

Dresses

Wrap dresses are the ultimate flattering choice—they add curves and a feminine line.

Dresses with defined waistbands or built-in ties highlight the middle beautifully.

Accessories

Long necklaces and scarves draw the eye down, elongating the body.

Belts (thin or wide) are essential—they transform a straight silhouette into one with curves.
