We have lots of families who come back year after year for Alder suits for their kids so we just want to warn you all that Alder have changed their sizing! Previously their sizing worked like this, 4-5, 5-6, 7-8 etc now they are like this 4, 6, 8 etc and we are finding that the new size 4 doesn't necessarily correspond to the old size 4-5. Confusing or what? If you need help don't hesitate to give us a shout.
Here is the new sizing chart:
If you need a smaller size then look at our Alder Toddler suits. There is no sizing chart for these but they are pretty close to the age they say in our experience.
This is where and how you should be measuring by the way....
For anyone who is particularly interested in how the age 10's are sizing up compared to the old age 9-10 Phil prepared the following spreadsheet for a customer which I thought would be useful to share (this is the accountant in him!)
And here is a picture he took of the old 9-10 on top of a new age 10 and you can see there is nearly 6 inches in the difference.
I hope I haven't confused you too much. If in doubt call into the shop or if you are buying online measure your child first! That will give you the best indication.
