What's the point of having a tail hole painted in the armor?

[Swishytail]

On male Miqo'te the tail go a bit to the side after leaving the body, while on female Miqo'te the tail left the body straight down.
Just ask a female Miqo'te to undress to compare the tails.

I think this is just a clever ploy to get all female Miqo'te to get undressed.
Well done.

This can be the new pickup line.
"I'm sorry, ma'am, but would you mind taking off your clothes? I just want to compare tails, that's all."
