Size 36N Swimwear
Also labeled UK 36JJ and EU 80N
In 36N swimwear, the details that matter most are band firmness, cup depth and torso length. Get the band right first and the rest is easier to judge. Our Swimwear Size Chart lists the UK and EU equivalents.
Keeping the 36N Band Level in Water
In a one-piece, a 36 band works together with the side panels, so check the fit under your arms as well as at the back. If the lower edge of the band folds over, it may be too narrow for your frame or set too tight. Fasten the band, lift both arms over your head, and check that the back has not moved.
Wear the suit for ten minutes before you judge it, then check that a mid-to-larger band still sits level. Swim fabric settles as it warms to your body, and a band that loosens then will loosen more in the water.
How 36N Swim Cups Should Hold You
An N cup is a very deep cup, so it needs coverage that reaches back toward the underarm and down to the band. A deep cup that fits well should let the center of the top rest close to your chest. Lean forward, settle each side into its cup, then stand and check the edges.
UK tags call it 36JJ. UK sizing doubles the letter here, so a US N reads JJ.
Neckline and Side Coverage in 36N
Neckline height and side coverage change how much of a 36N bust a suit holds. With a very deep cup, look for coverage that reaches toward the underarm so tissue does not slip out at the side. A higher neckline can feel more secure, but it should still lie flat without cutting in.

Frequently Asked Questions About Size 36N Swimwear
Which UK label matches US 36N swimwear?
Look for UK 36JJ or EU 80N; the JJ sits between a UK J and a UK K. Read the size system on every tag.
Should the straps hold up 36N swimwear?
No. The band and the body of the suit should carry most of the support, and the straps only steady it. If you need tight straps to feel secure in 36N, check the band first.
How can I tell if a 36N swim band is too tight?
It leaves deep marks, makes it hard to take a full breath, or pushes skin over its edges. On a mid-to-larger band, ease it to the next setting and check that it still stays level when you move.
How can I tell if a 36N swim band is too loose?
It rides up at the back, lets you pull it more than a couple of inches away from your body, or needs tight straps to feel secure. Fasten it firmer and recheck it once the suit is wet.
Do 36N swim tops and bottoms need the same size?
No. Size swim tops by your 36N bust and swim bottoms by your hips and waist. One-pieces are different, since the bust and torso both need to fit in one garment.
How should 36N swimwear feel after it gets wet?
It should feel close to how it felt dry, with the band still level and the cups still covering you. If the band feels loose after a swim, it was likely a little loose to begin with, which shows fast on a mid-to-larger band.
