formfitting

Formfitting, or form-fitting, describes garments or other items designed to closely follow the body's contours. Unlike loose or relaxed fits, formfitting designs emphasize shape, silhouette, and support, often using stretch fabrics and tailored patterns to maintain contact with the skin or underlying layers.

Materials and construction: The formfitting effect is achieved through elastomeric fibers such as spandex (elastane) or Lycra, knit fabrics with high stretch, or engineered woven structures. Patterns are drafted with negative ease to minimize looseness, and seams or darts may be placed to accommodate anatomy and movement. Finishing techniques like flatlock seams can reduce bulk and chafing, while gussets or paneling may enhance range of motion.

Applications and considerations: Formfitting designs are common in fashion, athletic wear, and medical or orthotic contexts. Benefits include freedom of movement, improved aerodynamics, a streamlined silhouette, and added support. Potential drawbacks include heat buildup, reduced ventilation, potential restriction of movement if too tight, and hygiene considerations with prolonged wear or sensitive skin.

Fit and measurement: Proper formfitting garments require accurate measurements of the wearer, including bust or chest, waist, hips, and torso length, as well as awareness of fabric properties and activity level. In manufacturing and tailoring, patterns are graded across sizes and may be adjusted with darts, seams, or panels to balance comfort with a close fit.
