30GG Fit Checklist (Quick & Practical)

If a 30GG bra doesn’t feel quite right, one of these fit points is usually responsible.

• Band: should feel firm and sit level on the loosest hook.
• Centre gore: should sit flat against the chest in most wired bras.
• Cups: should contain tissue without cutting in or collapsing.
• Wires: should sit on the ribcage and fully encase breast tissue.
• Straps: should refine fit, not carry the main support load.
