Sonja, 55, looked to be in deep conversation with her gal pals.
She narrowly avoided a nip snip in a see0through white number.
She was also caught taking a silly selfie during her time in The French Riviera.
Sonja wasn't the only RHONY star having a blast in Europe over the weekend.
Bethenny Frankel and her boyfriend Paul Bernon were spotted on a boat in the Amalfi Coast of Italy on Saturday.
The Skinnygirl founder dazzled in a multi colored dress and hat while luxuriating with her man.
Whose European outfit did you prefer more: Sonja or Bethenny's? Sound off in the comments!
