Custom Women's Seamless Cross-Back Full-Length Unitard | OEM Activewear

Women's seamless full-length unitard with a fitted legging body and multi-strap cross-back open design. Suitable for OEM, ODM and private-label activewear collections.

Product Overview

This women's seamless full-length unitard combines a fitted sleeveless upper body with full-length legs in one garment. The back uses a multi-strap cross-back layout with open sections, giving the otherwise simple one-piece silhouette a clear design focus.
Because the garment runs continuously from the upper body to the ankle, the size specification should be reviewed as a complete one-piece fit rather than treating the top and leggings sections independently.

Key Construction Details

  • Seamless full-length one-piece unitard
  • Sleeveless fitted upper body
  • Full-length fitted legs
  • Multi-strap cross-back construction
  • Open-back sections created by the strap layout

OEM / ODM Development

Buyers can customize color, yarn composition, fabric density, stretch and recovery, neckline, strap width and placement, back opening, torso length, rise, inseam, ankle opening, logo placement, labels and packaging. For brands developing a one-piece range, this style pairs with our seamless front-knot cutout bodysuit, which covers the shorter one-piece silhouette.
The target size chart should include enough information to control torso and leg proportions. During sampling, the buyer should check strap tension, back opening position, body length and inseam together. Our seamless unitard development guide covers torso balance, strap tension and leg-length checks for full-length one-piece styles.
