Jubilee grew up in Leyawiin, which is right between Elsweyr and Black Marsh (khajiits and argonians). So, I imagine that since they are everywhere in the town, she doesn’t feel out of place among them. However, she would agree that each person creates their own reputation, and doesn’t discount that they can be creepy (just like an evil nord or breton could be).
But this however, is not due to race, but the character of the person in the skin.
I tried to put in some argonian styled designs into her clothes, along with an imperial cape/sandal combo, and a khajiit bracelet.
