GG Cup Bras That Fit

GG is a full bust cup size in UK sizing. Fit matters more than the letter.

Updated . Edited by: Ilyass Ben Hakim.

Where to buy

Specialty lingerie shops with fitters stock the widest GG range. Online stores often let you filter by exact band and cup.

Professional insight

Fitters start with a firm band. Then they judge cup depth and wire width.

  • Most fit problems are a loose band and small cup.
  • Projected shapes need deep cups. Wide roots need wide wires.
  • The center gore should sit flat on the sternum.
  • Use sister sizes only as a starting point.

Sizing

GG sits between G and H in UK sizing. A G in one brand can fit like a GG in another.

US and European labels use different letters for the same cup. Always check which chart a brand uses before ordering.

Signs it needs replacing

  • The band rides up even on the tightest hook.
  • Wires poke through the channel.
  • Cups wrinkle or gape after washing.
  • Straps no longer hold their length.

Common questions

Is GG the same as H in US sizing?
Not always. US brands vary, so compare each size chart.
Why is GG hard to find in big stores?
Many mainstream lines stop near DDD. Full bust brands go further.
Should I get refitted?
Yes, after weight change or pregnancy. Size often shifts.
