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.

For detailed troubleshooting, follow our Bra Fitting Advice.
