Sessions Girl's Star Pant

My daughter started her first skating lesson during summer. I thought Amazon should be the perfect place to order. The first pair came here, it's so.... so big. BTW: there's no size chart on the webpage. I tried to replace with a smaller one, but amazon doesn't provide the replacement service for this item. What I need to do is to order another pair of smaller size and return this pair. I ordered again, and today is her 2nd week of skating, but the pants are still on it's way.

Size is way bigger than the size should be but it is made very well!

Bought size S for my 7 year old gal (4 feet tall). Pants too long (by at least 10cm). A shame, cos it's a nice pants and I got a good price for it.
