They're not going to wear their uniforms again until SEPTEMBER. Monday is a non-uniform day... and even if it weren't, it would be for them. I AM SO DONE WITH UNIFORMS FOR THIS YEAR. I'll take a similar picture first day of school, of course.
Note the jumpers. I look at jumpers as a sensible and practical way to keep their shirts clean. Navy doesn't stain. I'm apparently alone on this, as few of their (female) classmates wear jumpers, instead preferring to wear skirts or shorts.
