36JJ Bras

In a 36JJ, the 36 refers to your ribcage measurement and the JJ to a bust roughly 14 inches larger than it. If you've been fitted in a US brand and are shopping a European label, expect the letter to shift — the volume stays the same, the notation doesn't.

How a 36JJ should fit

A 36JJ is a full-bust size, and the engineering matters more than the label. Wide side wings, a firm band with four hooks and seamed cups will outperform a prettier bra with thin straps every time.

Sister sizes to try if 36JJ isn't right

• Band feels loose but the cup is right — try 34K
• Band is comfortable but you're spilling over — go up to 36K
• Band digs in — 38J gives the same cup volume with more room

Best 36JJ styles

Look for side support panels, which push tissue forward and stop it migrating under the arm — the single most useful feature at 36JJ. Full cup and balconette shapes both work; strapless is harder at this size and worth trying with a longline style, which spreads the weight across a wider band.
