A rectangle body type, sometimes called a straight body type, is defined by a bust, waist, and hips that are similar in width, with little natural waist definition. The frame appears balanced but straight.

Rectangle shapes are not lacking curves. They simply benefit from intentional structure. The goal is to create softness, shape, and dimension without forcing curves that don't feel natural. Choosing the right dress makes all the difference.

How to Know if You're Rectangle Shaped

• Bust, waist, and hips are within 1 to 3 inches of each other.
• Waist has minimal indentation.
• Overall silhouette looks straight from top to bottom.

Example

Bust: 36
Waist: 33
Hips: 36

Common Fit Frustrations

• Dresses feel boxy or shapeless.
• Waistlines don't sit right or feel necessary.
• Straight cuts look flat instead of flattering.
• Outfits feel unfinished or overly simple.

When a dress has no dimension, it mirrors a straight frame instead of enhancing it.
