There used to be a rental shop in the Dune Center in Al Diyafah Street, Satwa...
That place has long gone but I was told recently that there is another place on Al Dhiyafa Street so I suggest you go and walk the length of that street and ask a few people!
Does anyone know where DH can rent a decent Tuxedo for this Friday? He's verging on the slighty panic stricken side. Anything for a quiet life! Thanks!
