Kassim

Costume 1

turquoise harem pants (see below for links)
turquoise long sleeved collarless shirt. Collarless shirts include kurtas, henleys, or you could buy a turquoise dress shirt from a thrift store and cut the collar off.
brown sandals

Costume 2

long white skinny pants (NOT leggings). Here’s a link to boy’s white skinny jeans, these would be ok too.
long sleeved white collarless shirt (here’s a link to an adult sized one). You could buy a white or off white kurta instead if you prefer.

Females playing this role will require a wig

MYTP will be adding pieces to both costumes; there may be a rental fee for these.
