Skirts for 6th form

[AmusedViper]

Hi, any idea where to find a fashionable skirt for 6th form? Can be any colour but must be no more than 3 inches above the knee. We can't find any that don't look like junior school skirts. No denim allowed. Thank you.

Does it have to be "office wear" style?
Because H+M and Primark usually have skirts in that style.

Mine gets all hers on vinted. Zara is one shop she gets quite a lot from.

Thank you, I'll have another look. No the guidance was just smart and no mini skirts. Somewhere between mid thigh and below knee, but I think they'd prefer longer end.
