Hi Kubur,
Re the belt. I do not have this piece any more but from memory the belt is "man size". BUT it must be remembered that the European man is generally of bigger size than the average Asian/Middle Eastern person, so lets say in the MODERN European form, it is either a small man or large child size
The other comment I would make is that the Yemeni made items are NOT Meccan, but are purely a copy of the form, so could really be any size the maker wishes to construct.
