Tie or not to tie

Although I'm not so sure about the skirt as it looks too senior for me I like the blouse and that tie as it isn't too far removed from  the one I had at Junior school which was a  off white and red one that I like to wear.
Maybe something like that but with a skirt more like this might work:

That's more like the junior pleated skirts I'm happier with as they were a part of the me through age play I wish to be back in the headspace of.
