The only problem I have is the name. Please, ban the fucking word from the English language, especially when referring to usually girls' or women's clothing. Ugh.
But those just look like stretchy gym shorts to me. We had to wear them at my convent school, in lovely bottle green, either in the gym teamed with an airtex top, or under our kilts outdoors for hockey or netball.
I have a DD3 in primary school; I don't bother with shorts under her skirt, so I get what the OP is saying. I wouldn't think of them as anything other than - shorts.
