woman dress code for Sharjah

Sharjah is known to be more conservative in terms of dress than Dubai or Abu Dhabi, but it seems like that would be fine to me.

don't warry ... it is ok ofcourse it is not like Dubai but you will be fine

You can wear a decent dress as long as its not fitted.
To make it sure wear trouser and decent shirt and blouse.
mini skirt, short and sleeveless are not allowed.

Keep your shoulders and upper arms covered ; you don't need to wear long sleeved tops. If skirts, they should be mid calf length. No shorts for men either by the way.

And 3/4 length trousers / cut-offs are fine also.

The important bits to keep covered are knees and shoulders.
