Sizing

Which size to choose

The romper is cut roomy through the body so it layers over a vest. If you are between two sizes, take the larger — babies grow through a size faster than anyone expects, and a little length at the cuff is easily turned back.

Buying as a gift?

Take 6–12m. It is the size most often missing from a new parent's drawer, and it buys them a few months before it is needed.

Measuring at home

Lay a romper they already wear flat and measure across the chest just under the arms, then from the shoulder seam to the crotch. Compare against the table.

Will it shrink?

Pre-washed cloth, so expect no more than 2% after the first cold wash. Dry flat rather than in a machine and it will hold.
