Why is "bra" singular and "panties" plural?

[Aggie]

Aggie minds want to know.

I do not know, Aggie, but that's a darned good question!

"bras' in french means 'arms'.so says wiki....we mostly all have two of them.
I'm just wondering why panties are called a 'pair'....as are slacks and trousers...I've never gotten two...!
