Hello,
Thanks for your replies. I had looked at the school uniform websites and they only had what was available in my local uniform school which didn't fit. Thankfully DH and DD found two pairs in New Look today, one pair formal and one pair which are a snug fit - lets hope the school don't notice

DD did find a proper pair of school trousers only in black which she wanted and which were the only pair to fit younger DD who is going to a different school so that didn't go down too well ... Can't believe the summer has gone so quick.
