A 16G bra size represents a band size of 16 (equivalent to an 85 underbust in EU sizing) and a G cup, which offers generous cup volume for fuller busts. This size suits those with a larger bust and mid-range torso, ensuring both support and comfort when fitted correctly. At The Foundation, we specialise in fitting hard-to-find sizes like 16G, because we believe every body deserves support that feels just right. Our bras are tailored to Australian sizing, reflecting the specific needs of our local clientele.

Quick Sizing Guide: How to Measure at Home

Under bust (band size): Measure snugly around your ribcage. If you get an odd number, round up to the nearest even number. For example, if your measurement is 79 cm, round it up to 80 cm — that’s your band size. For extra guidance, visit our visual fitting guide.
Over bust (bust measurement): Measure around the fullest part of your bust. Subtract your band measurement to determine your cup size.

This simple fitting matrix helps determine your body size and cup size. Check our size conversion chart for additional accuracy.

Sister Sizes and Fit Tips

If 16G isn’t quite right, try sister sizes such as 14H or 18F. These sizes share the same cup volume but differ in band size, perfect when your body fluctuates or your current bra sizing needs adjustment.
