Sizing Guide

Buying baby clothes to fit can be a bit of a mind field!

Each brand and each country seems to have its own manufacturing guidelines which are not always converted into NZ sizes.
A variation in styles and personal preferences also means that one size doesn’t necessarily fit all!
Perhaps the best indicator to help buy the correct size clothing is to go on your baby’s height, rather than their weight or age.
If in doubt, it’s always best to go a size bigger than you think you need. Babies grow fast!
Use our baby clothing size chart to help you buy the right sized clothes for your little ones, especially when you're buying online or from overseas.

How do maternity clothing sizes work?

Maternity sizes work the same as regular clothing sizes. That is, if you're normally a size "small," you'll still be a small in maternity sizes. Same thing with numbered sizes: If you were an 8 pre-pregnancy, look for items in that size.

And when it comes to jeans, particularly the designer sort that are labeled by waist size (for example, 28-inch), you'll still shop for a pair in that samesize – just the maternity version. (True, your waist is no longer 28 inches but designers make it easier to find your current size by sticking with your pre-pregnancy number.)

Don't give in to the temptation to buy nonmaternity clothes that are a size or two larger than you normally wear, as if you were simply packing on the pounds. You'll end up with ill-fitting clothes that aren't nearly as flattering as properly tailored maternity wear. Designers make maternity clothes with extra fabric and details that keep you comfortable, like stretchy belly panels or empire waist ties, while flattering your body.
