• Band: should feel secure and sit level on the loosest hook.
• Centre gore: should sit flat against the chest in most wired bras.
• Cups: should contain breast tissue without cutting in or gaping.
• Wires: should sit on the ribcage and fully encase tissue.
• Straps: should assist with fit, not provide primary support.
