I read that Landmark had knee high socks in stock, for only Php 199. On the magazine, it said they have a pair in grey but when I checked it out, they only had it in black, white, and green?

Today I tried them on but have no idea what to wear them with yet. The first thing to avoid is looking like a school girl ala cosplay. So I am here researching about them.
How would you wear your knee high socks?
