I would say that Oda tends to reutilize the same physical structure (proportion of the face). But here the question is:
1. Can you recognize a women in One Piece on the first sight?
2. Are the design of women in One Piece a good reflections of the characterization of the character?
3. Are the design of women in One Piece efficiant?
The answer to all those questions is:
Yes
