I believe Featherweight and Middleweight do not apply to womens wrestling, those weight classes are associated with Men's Lucha Libre and Boxing. To my knowledge in Women's Pro-Wrestling there are only 2 weight classes Jr. and Heavy. I'm not sure what the limit is but it could be easy to find out the weights of these "jr." women's wrestlers: Chaparitta ASARI, Ai Fujita and Mika Akino (aka AKINO & noki-A). Once you find that out it should be simple to recognize the weight limits.
But hey, I could be wrong
