It's more the hairstyle than the clothing... scratch that it's only the hairstyle. We've never seen Wendy wear anything that revealing (except perhaps the Punishment Game omake), not even her bathing suits.

I really don't think that Ohpichus is a replacement or former Zodiac who got destroyed. The snake-bearer constellation is a star constellation just like any other of the 88 ones listed in the Uranometria (the star atlas in reality, not the spell), but it's not considered an actual part of the twelve signs (something to do with the 30° spacing and thus the one month cycles, if I got that right) even though it also is on the ecliptic.
