As the title says - been conned in to a 'matchy matchy' set by dd who is 9 early next year. I'd say she average to slightly tall for her age and a bit more sturdy than her stick like sister. Does any one have any idea on how the sizing is. I get the feeling it's going to come up small and that ordering a 9-10 will be a waste and be grown out of promptly. Might be better with the 11-12 . Can anyone confirm??
