Stripy school summer dresses where can I find them?

[TennisFan]

I can't find any blue/White striped summer dresses for
school. It needs to be cheap as possible so no fancy school outfitters. Tried M&S and Sainsburys so far as they are handy to me.
Does anyone know about the other stores such as Asda, Tesco or Debenhams?

Thanks

M&S have them online

I asked a similar question a couple of weeks ago - apart from M&S (theoretically in store, really only online) there's hardly anyone doing stripes any more. I was told that Debenhams and John Lewis had them instore last year but I know they didn't have them online then or now.

There was one A-line style available online from a few suppliers, eg here
