Alvida is a prime example: While she was ugly it was okay to beat her but the worst that happened to her after she ate her DF was being caught by Smoker.

As for Monet, Zoro just sat back and let Tashigi do the fighting for the most part. When Zoro seriously hit her she had just bitten Tashigi and was still in her ugly form. So it was "okay" to attack her.

Zoro cutting her into half was only the extreme version of "Usop hitting Perona with his balloon hammer": Since Monet is a Logia user and it didn't really damage her physically. It "merely" traumatized her.

Tashigi got the final attack on her in the end.

So my point is: Beautiful women only take physical damage from other beautiful women (Nami/Kalifa or Tashigi/Monet) or bad guys (e.g. Arlong, Spandam or Vergo).
