16JJ Bra Size – Comfort and Support for Every Curve
Understanding 16JJ: Band and Cup Size Explained
The 16JJ bra size is specially designed for those with a band size of 16 (equivalent to a 38 in UK sizing) and a cup size that’s significantly fuller. The "JJ" cup offers expansive bust coverage and depth, ensuring both comfort and support without compromising on style. Perfect for fuller busts, this size ensures your bra works with your body, not against it—featuring design details like wider straps, deeper cups, and reinforced side support for all-day confidence. Whether you're looking for sports bras, nursing bras, or strapless bras, The Foundation has carefully curated options in this size.

Sizing Guide: Measure with Confidence
Use a soft tape measure and follow these simple steps:
- Band Size: Measure snugly around your ribcage, just under your bust. Round to the nearest even number.
- Bust Measurement: Measure around the fullest part of your bust without squashing. Keep the tape horizontal and comfortable.
The difference between your bust and band measurement determines your cup size. Refer to our bra size chart to find your exact fit. You can also visit our Fitting Room for personalised advice.
Sister Sizes to 16JJ
If your usual size isn’t available, try sister sizes like:
- 14K (smaller band, larger cup)
- 18J (larger band, smaller cup)
These options maintain a similar cup volume with slight band size variations, and our expert bra fitting team can help you find the right one.
