School tights for Spring

[MilestoneMum]

Does anyone know where I can buy navy or grey school tights which are thinner than the winter ones ?

My DD wears Primark grey opaque tights to school which are great, think they are 40 denier.

M&S do navy opaque school tights (I.e. not the woolly ones), although DD1 (12) wears the small size adult navy ones, also from M&S.

Dd (secondary age) wears Primark or John Lewis grey opaque tights all year round as she doesn't like the woolwn ones.

M&S used to do thiner grey ones that were really soft, DD2 used them all year in Y6, but surely primary DCs swap to long socks if it's faintly warm.
