I've blown hot and cold on this one for many years.
When I was Headmistress, woe betide any girls who didn't wear their kilts properly, lengthwise!
Now, in the 21st century, provided the tracksuits are school branded, and every one has the same, I think it's a good idea.
Teaching abroad for a while, where pupils don't have school uniforms at all, I can't say I noticed any deterioration in behaviour or discipline.
I am delighted to hear someone with practical experience of this. I really don’t understand why we are so obsessed with school uniform in the UK, unlike our close neighbours in Europe and even in the US. They seem to have overcome all of the problems that British schools claim will arise if there is no school uniform.
