You can buy clothes throughout the city at little suq areas or clothing stores. Here are a few of the bigger stores:
City Max (located on Shariah Sitteen)
LARGE two story store with men’s, women’s, children’s clothing and shoes. They also sell hijabs and khimars, toys, baby items (strollers, carriers) and oils and perfumes.
Master Mart
( I have seen two of these, one on Shariah Haddah). Never been there but have heard they are supposed to be reasonably priced).
Shumaylah Hari (located off of Shariah Haddah)
In addition to clothes, sells food and household products.
