Maternity wear sizing

  • We advise you to buy your pre-pregnant size. Styles have been cut to allow for your changing shape but should fit the following approximate figure measurements.
  • Please note that garment measurements vary according to the design.
  • Items sized S, M, L are cut in extra stretchy fabric to fit both size groups.
  • Lengths are calculated from under the waist band on Skirts, nape of neck to hem on dresses and inside leg on trousers and shorts.
  • Elasticated waist bands on Maternity Clothes (where stated) have adjustable button elastic. For comfort and fit simply adjust the width by moving from one buttonhole to the next as you grow and take in again after the birth.

Maternity and nursing bra sizing

Guidance in choosing your nursing bra size

If you find that your measurements don't correspond to the sizes listed below we recommend that you visit one of Our Stores for professional fitting. We carry a wider range of sizes in store and can advise you on the best style for you.

Once the milk comes in, the cup size will increase by at least one size, so nursing bras purchased before the birth should allow for this.

The rib cage size should reduce back to its pre-pregnant size within a few weeks of the birth
- which is why nursing bras have so many back size adjustors. When trying a bra before the birth, ensure that the back is on one of the loosest fittings, to allow you to tighten it as rib cage retracts after the birth.

The nursing bras that fit before and after the birth will possibly not fit a couple of months
later once a breastfeeding pattern has been established. You may need to purchase smaller bras at this stage.


What will I need for pregnancy & breastfeeding?
As a minimum we suggest:

  • 2 maternity bras and 2 nursing bras
  • Or 4 nursing bras (which can be worn during the later stages of pregnancy)
  • 2 sleep bras (unless the style chosen for the above is also suitable for sleep)
  • 2 packs of nursing inserts
  • 1 pregnancy support pillow
  • Mattress protection sheet

In preparation for breastfeeding we also recommend that you have a supply of nipple cream. Camillosan is perfect and available from all chemists.

Baby & children's wear sizing

We are proud of our unique designs and we concentrate
on the following issues during development:

  • Comfort - we stick to natural fibres (eg cotton or wool) wherever possible and test all fabrics for softness and suitability for delicate newborn and baby skin.
  • Practicality - we know how difficult it is to dress a wriggly little baby and have designed many innovative ways of making this often tricky task much easier - such as wrap over bodies, sleepsuits that open completely flat and wrap over knits.
  • Functionality - we aim to think as a parent & provide functional items, for example there is no toddler in the world who will not want to splash and even sit in a nice deep puddle. With this in mind we developed rainwear, which was totally waterproof but also breathable (so the child doesn't get hot and sweaty). Most rainwear is either shower proof and breathable or waterproof but made of non-breathable PVC. This is just one example out of hundreds of styles where we would not accept a compromise & sought the perfect solution even if, sometimes, it means the items are a little more expensive than less effective versions.
  • Style - dressing your baby or child should be a huge pleasure and we make sure that our designs not only incorporate all of the above practical elements, but are also totally adorable. Even functional clothing like our Polar Fleece all-in-ones or our swim nappies have a real 'ahhhh' factor!

Children's accessories sizing

(socks, shoes, hats etc)

Our hat sizing chart is based on your child's head circumference and we recommend that you try to measure your child's head before ordering a hat. However, as their heads grow rapidly in the first couple of years and are different shapes and sizes, our sizing chart is meant to be a guideline only.

To measure your child's head circumference, wrap a tape measure around your child's head just above the eyebrows. Insert your index finger inside the tape measure to allow extra room for growth. Read the measurement and compare with the size chart below.

Sleeping bag guide

Why use JoJo Sleeping Bags?

  • A sleeping bag prevents your baby from pulling the covers over their head or sliding down under the blankets.
  • A sleeping bag stops your baby kicking off the covers, getting cold and crying.
  • You can cuddle your baby to sleep in their bag, then lay them in their cot without waking.
  • Wherever your baby is sleeping they will feel safe and secure in the familiar comfort of their sleeping bag.
  • Use our multibuy offer and buy 2, so when one is in the wash your baby is still comfortable and feels secure.
  • Most importantly if your baby gets a good night’s sleep, so will you!

Children's swim nappies, bubbles, shorts & sunhat sizing

Most local authority swimming pools now demand that babies use swim nappies of some sort and JoJo swim nappies have consistently been highly recommended for their functionality and style.

For many years we have been extremely successful with our baby swim nappies and matching sun hats and accessories. We started selling swim nappies at a time when they were unknown in this country and parents used to put a normal nappy underneath their baby's swim suit. This resulted in a nasty water logged nappy, which did not perform and really weighed the baby down - impeding swimming and free movement in the water.

Our swim nappies are cleverly constructed so that they contain a polyurethane barrier (or layer), which sits between the outer fabric and the cotton lining. This barrier is waterproof and prevents 'accidents' from leaking out. The nappies are designed so that the elastic around the legs is tighter than on normal pants - it should not be uncomfortably tight but should fit snugly. It will not prevent liquids from leaking out but does keep solids in.
