هو رجول أسكتلنحي
Do not tell a Scot he’s wearing a skirt! It’s a kilt. Many Englishmen have died making that mistake.
George is a man, how can he have a skirt?
Lots of ways! See aldamen's post, for example.
A skirt and George? Really?!
Does the gender of the color not change according to the object it refers to? I would expect it to be زرقاة. Or am I missing something?
You are right, the colour must match the gender of the noun. However most colours have irregular feminine forms.
Blue masculine is أزرق and feminine is زرقاء
