Not sure of your size?

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

About Size 40J Bras

A 40J is a 40 band with a J cup — a specialist fuller-bust 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 40J for fuller busts, part of our full 40D–40K range. Not sure 40J is your size? Book a personalized fitting and we'll get it sorted.

  • Band first. The 40 band carries the support — it should sit snug and level on the loosest hook.
  • Sister sizes. 40J sister-sizes to 38JJ or 42HH — same cup volume, different band.
  • Personalized fittings. Pan-India fit help, in person and online — no pressure, no jargon.

Questions, answered

What is a 40J bra size?

The 40 is your band — roughly a 40-inch ribcage — and the J is the cup, about 13 inches between your underbust and fullest point. Put together, 40J is one fitted size, not two separate measurements.

Is the band or the cup more important in a 40J?

The band. In a 40J, the 40 band gives most of the lift and support; the J cup just needs to hold your volume without spilling. A loose band is the most common fit problem, so that's where to start.

Which is bigger, 40J or 40JJ?

On the same 40 band, cups run HH, J, JJ — so a 40J is one cup fuller than a 40HH and one less than a 40JJ. Same band, just more or less cup depth.
