Can you tell newly qualified teachers by their cheap suits? And why do more mature staff look as if their clothes have been yanked from a bin outside an Oxfam shop?
This was the debate on The TES online staffroom, as teachers quibbled over whether you can tell more than a colleague's fashion preferences from their garb.
"I know one NQT who recently bought one suit and wears it everyday," mused one message writer. "Then there are teachers who have been teaching for 30 years and look like they should be going on a picnic, not to work."
"I teach drama, so am required by law to wear fabulous clothes, big earrings and funky shoes," opined another.
Pity the mug who invited others to guess his teaching background from his photo. "I'd say 26 years in PE?" offered one, mercilessly. So much for professional solidarity.
