I've only came across to this many of times, but finally decided to check in to suggestions and see what other would have to say upon this too.

Pretty much the newest manes coming into the game have an altered tail floof for the male (when you're viewing the male theme) however, when you switch to females, their tail floof is the same and not altered in any way or form, so to kinda figure out the mane type you'd have to look upon their statistics.

However, I am not very artistic to show you guys examples of what I mean, but just like how the males have the tail fluff changed with the mane shape, I feel the lioness tail fluff should as well be longer, skinnier, thicker, etc...

It's like a small adjustment to the female image, not like similar to a custom decor but just something to match their mane shape for the males.
