Dd is 4.3 and will be starting school in September. I was looking at the uniform in M&S yesterday and found a skirt for age 3 but the waist was far too big (and just fell straight down). I was wondering if anyone knows of somewhere that sells uniform for very slim children. I'm not quite sure what her waist size is (will check later) but she can easily fit into 12-18 months skirts (they're just too short) and has a tiny bum. She's just over a metre in height.
