If your husband is just visiting then ready made will have to do. No time to get one made. I don't think he will know about selecting fabric for the abaya and the shayla and then how to design it. Hope he knows your measurements!

More expensive ready made ones are available at malls. City Centre amd Landmark malls have a shop called Motahejeba. Hyatt Plaza mall has a shop called Dary. I think starting price for a reasonable one might be around QR 1000 for both the abaya and shayla.

Good luck to him! My husband wouldn't know where to start at buying an abaya. He is, however, an expert on thobes and ghuttras!
