36J Bras

36J pairs a 36-inch band with a J cup, which works out at about a 13-inch gap between underbust and bust. Sizing varies more between brands than most people expect, which is why two bras both marked 36J can fit quite differently.

How a 36J should fit

At J cup, weight distribution is the whole problem. A 36J needs a taut band, a centre gore that sits flush against the sternum, and cups built in three or four panels — a single moulded cup simply cannot hold this volume in shape.

Sister sizes to try if 36J isn't right

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

Best 36J styles

Look for side support panels, which push tissue forward and stop it migrating under the arm — the single most useful feature at 36J. 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.
