Looking through the wiki and good lord why do all the female characters have visible nipples

Might have to do with the skin tight attire worn, if you mean the... high level of detail of the physical form pressing against said clothes.

Though a more elaborated guess is that they originally wanted to include actual nudity, but desired to sell the manga at a different rating. A different way of censoring made in late stages possibly.
