Should I explore sister sizes to my JJ cup?

While it's just sometimes not possible to find your size at the time, sister sizes can be a great alternative. Your sister sizes are one band down with K cup (e.g., 14JJ = 12K) or one band up with J cup (e.g., 14JJ = 16J). If your band rides up or feels loose, trying a smaller band with K cup often provides better support. If your band feels restrictive, a larger band with J cup might be more comfortable. However, at JJ cup, proper fitting is essential because small adjustments make significant differences in support and comfort. Visit our Melbourne bra fitting service where our experienced fitters can assess your breast shape and support needs to determine your optimal size. No bookings required - just drop in during store hours and we'll help you discover which size in our 8-30 band, A-K cup range works best for your body.

JJ Cup Bra Measurements

JJ cup bras are designed for a 36-38cm difference between underbust and overbust measurements, scaling up according to band size (for instance, 12JJ: 73-77cm underbust/109-111cm overbust; 16JJ: 83-87cm underbust/119-121cm overbust).
