I'm an exmuslims so I have just as much exposure to Islam and muslim societies as you do.

The clothing I had in mind is a prayer gown called a "telekung" and its used by women in south-east asia. Sort of like an abaya but the headwear is long and goes below the hips. From what Ive seen of mixed gender prayers, many women wrap clothing around their hips to have the same effect for when they bow down.

Wat do women wear when they pray where you live that has you thinking it would be inappropriate if they lead?
