Yep, I tend to get one of each. They grow sooo fast! get Chelsea to wear the size 6 on her first day of school and suss out how other girls look in their uniforms. If, like at my Dd's school, other parents are also keen to economise, then you will see a lot of girls in massive dresses too! If however all the girls' dresses seem to fit nicely then I'd suggest buying a second hand dress as well. I usually buy an extra second hand dress for Verity each season. Her school has a wonderful second life uniform shop with lots of second hand dresses at usually 1/3 the price. Thankfully Verity has started to slow down growth-wise. you will find that between 7-11 girls grow soooo fast. Not so bad at Chelsea's age but watch out! Also, with regards school shoes: check out the Airflex brand... they are the best!
