Communicating Plus, Petite & Maternity sizes in addition to "regular" sizes? - petite plus size maternity

We are launching a fashion line, and there was something really bothers me is how to distinguish between "normal", "more" and "Small-size clothing. I feel like an insult to their choice of clothes than to distinguish more" and I just wanted to know if there is another way to communicate these opportunities.

Thus, there are three options:
"Regular" size
"More" and "small"

Is offensive to say:

Eclothing
Eclothing Plus Store
Little Shop Eclothing

So "eclothing" stands alone for the "normal size", add it to the other sizes "more" or "light" or "motherhood" later in eclothing. I do not know yet how it seems offensive to me? "Am I mistaken, Petite Plus and is accepted by the industry and accepted the conditions for women?
