Though this is a children's tee, the 12 is an equivalent to a womens size 6, and the 14 is the equivalent to a womens 8 or 10. If unsure on sizing, we would suggest going down a size. This style in particular is runs very large.
Once upon a time a friend of mine went through a phase of shortening down everyones names to something as Australian as possible. My horse Jericho also became a victim of this renaming, and so the nickname 'Jezza' happened. This was later shortened to 'Jez'. Then the other horses too became victims, and here on this tee we have my competition horses and their fabulous Australian nicknames, 'Jez, Dez & Pez' (Jericho, Dexter & Pinot).
Unfortunately no washing this in over 30 degrees Celsius dudes
