Not sure of your size?

Three ways to get the fit you've always wanted. Expert guidance, wherever you're most comfortable.

About Size 30JJ Bras

A 30JJ is a 30 band with a JJ cup — a specialist, very deep cup. The band does most of the work (around 80% of your support), so if it rides up at the back or the straps dig in, it's the band to fix, not you.

We cut 30JJ for fuller busts, part of our full 30D–30K range. Not sure 30JJ is your size? Book a personalized fitting and we'll get it sorted.

  • Band first. The 30 band carries the support — it should sit snug and level on the loosest hook.
  • Sister sizes. 30JJ sister-sizes to 28K or 32J — same cup volume, different band.
  • Personalized fittings. Pan-India fit help, in person and online — no pressure, no jargon.

Questions, answered

What is a 30JJ bra size?

The 30 is your band — roughly a 30-inch ribcage — and the JJ is the cup, about 14 inches between your underbust and fullest point. Put together, 30JJ is one fitted size, not two separate measurements.

What does a good 30JJ fit feel like?

The 30 band should sit level and firm on the loosest hook — it does around 80% of the support. The JJ cup should hold you fully, with no spillage or gaping. If the band rides up or the straps dig in, the band's too loose or the cup too small. Book a fitting if you're unsure.

What does the work in a 30JJ — the band or the cup?

The band. In a 30JJ, the 30 band gives most of the lift and support; the JJ cup just needs to hold your volume without spilling. A loose band is the most common fit problem, so that's where to start.
