check to see what size those items are and order the next size up.

If a garment is sized in chest measurements this is usually a ‘to fit’ measurement. In other words, this is not the size the garment measures but the size your child measures.
Have a look at the size specs links on our product pages.
These are garment specifications and size charts supplied by the manufacturers. Some of these will tell you what size you need for a specific measurement, others may tell you to measure and compare actual sizes i.e. collar, chest, waist etc.

Imperial or Metric?
Despite metric being widespread a lot of clothing in the UK still utilises Imperial measurements of inches/feet.
Collar sizes, chest sizes, waist sizes and leg lengths/skirt drops are nearly always in inches.
