Size 38N Swimwear
Also labeled UK 38JJ and EU 85N
38N swimwear pairs a larger band with a very deep cup, so the band has to stay firm while the cups hold real depth. Start with your usual bra size, then check how the suit feels once it is wet. Our Swimwear Size Chart shows the matching UK and EU labels.
When a 38N Swim Band Rides Up
On a 38 band, the band carries a large share of the support, so it should feel firm without rolling or digging. If the lower edge of the band folds over, it may be too narrow for your frame or set too tight. Look in a mirror from the side to see whether the back sits lower than the front.
Check the leg openings and shoulders together. If a very deep cup pulls the front down while the straps dig, the torso may be short, so look for a longer body before changing your bust size.
Finding Enough Cup Depth for 38N
Wide straps can feel kinder on the shoulders with an N cup, as long as the band is doing its share. Check the fit once more after you move, because a deep cup can shift if the band loosens. Spilling at the top or sides usually points to a cup that is too shallow.
Its UK label is 38JJ. The doubled JJ sits between a UK J and a UK K.
When a 38N Suit Shifts in the Water
A suit that fits standing still can shift once you are active. Walk, reach overhead and bend forward in your 38N suit, then look at the cup edges and the back. If anything slips, fix the band first and the straps second.

Frequently Asked Questions About Size 38N Swimwear
How does 38N swimwear convert to UK and EU sizes?
UK labels print 38JJ and EU labels 85N, with JJ standing in for the US N. Follow the system printed on each label.
What does it mean if a 38N swim cup edge cuts in?
It usually means the cup is too shallow for your depth, even if the letter is right. With a very deep cup, look for cups with more depth or coverage rather than a tighter band.
Should the straps hold up 38N 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 38N, check the band first.
How can I tell if a 38N 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 larger band, ease it to the next setting and check that it still stays level when you move.
How can I tell if a 38N 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 38N swim tops and bottoms need the same size?
No. Size swim tops by your 38N 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.
