Hi Farouk, thanks for the good wishes for Thayanee.
No she doesn't do the "goth look".In Thai culture, black is reserved solely for mourning and gangsters. No i'm not joking, loan sharks (a huge industry) and drug dealers etc actually wear black like the bad guys in so many b grade TV shows and movies here and elsewhere. Every time there's a big arrest on TV they are always in black,to the point the BIB (boys in brown / police) will do random check on young guys wearing black

Thais also like bright and cheerful colours so black is not popular. Having said that, in major cities like BKK and Khorat, I have seen an increase in Goths and also Punk / J Punk fashion which is also dark. Also in general fashion among the 20-30somethings black is becoming a little more popular as western influence takes hold.
The cats eyes aren't that big over here because they already have the beautiful almond shaped eyes and pupil colour is usually very dark brown to black. (Thais actually love Thayanee'seyes because they are hazel)
They do have a thing for the Egyptian style of mascara at the moment like you see in Hieroglyphs,extending from the outer edge of the eye towards the side of the head.
Hope that answers your questions properly
God Bless
