As so often with the French language, the gender of the definite or indefinite article appears to defy logic. Why is the word moustache feminine not masculine? Were Frenchwomen in olden days notable for having hirsute upper lips? Perhaps so. And perhaps we should praise the French for being so understanding of a feature that, in other less tolerant cultures, might have resulted in the unfortunate women in question being paraded as freaks.
In a sideshow, perhaps.
