Repeating outfits

How many teaching outfits do you have? I have seven outfits that I rotate. One of the children in my class commented, "Miss X, my previous teachers used to wear different clothes." Another told me, "You wore that yesterday". I hadn't worn it yesterday, I had worn it the previous week.

Now it's made me conscious that I don't have enough teacher clothes and that I'm wearing the same clothes every week (of course washing inbetween.)
