Are knee-high socks slutty?

So today I wore a long sleeve floral top with a black skater skirt and knee-high black socks... I thought the outfit was really cute & it didn't seem provocative at all... I've always dressed really classy! But my french teacher kept like looking at my legs with a look of disappointment and I noticed people were looking at me a lot more than usual... Especially my legs... And one girl said "aren't you cold in that outfit.." ... I know its fall but i wore the socks to keep me warm!
