[PFS] Building a flashy duelist (not the prestige class)

[mechaPoet]

Hello friends. So, I've come to you all to help me brainstorm how to fulfill a character concept: I want to play a character analogous to Julie d'Aubigny, aka La Maupin. Here's a link to how utterly cool she was.

Here's the core of the concept:
-Uses weapon finesse (or equivalent), is good at it
-Charismatic
-Likely a non-lawful alignment, or at least someone who scorns tradition
-Opera singer (or some other performer)
-Good "face" skills

To me this sounds like the new ACG Swashbuckler, but bards are really the only ones who can seem to make practical use of the perform skill. Perhaps some sort of bard/swashbuckler multiclass? Also, I'm more interested in the core of this concept, rather than creating La Maupin literally. That is, this character doesn't necessarily have to be a human with a rapier, but does have to be a badass finesse fighter who cares more about making out with hotties than caring about what people think of them. I briefly flirted with the idea of a dwarf swashbuckler with Slashing Grace (Dwarven Waraxe), thinking that a dwarven Dex-fighter is pretty tradition-breaking enough, but I'm open to suggestions.

Since this is for PFS, point buy is 20. Allowed sources are the core rulebook, Advanced Player's Guide, and Advanced Class Guide. I have some floating credit I can apply to a new character, so the build could start at level 1 or as high as level 2.

She could also be a ballerina using Dance. Two levels of Perform (Dance) are needed for Dervish Dance and three will improve fighting defensively.

In PFS, Perform can be used for a day job check.

There are several traits that make Perform a class skill.

Unfortunately, I don't have the Inner Sea World Guide, so Dervish Dance is a no-go.

As far as "good at finesse fighting" goes, I'm thinking either a Swashbuckler or a Daring Champion Cavalier, both from ACG, perhaps with the Slashing Grace feat to get dex to damage? The Weapon focus might be a little harsh, though, depending on how many feats I can spare.

It sounds like a straight-up swashbuckler to me. Possibly an Inspired Blade to get bonuses on rapiers.

Swashbucklers are charismatic, have Perform as a class skill, get free Weapon Finesse, have Diplomacy, Intimidate, and Bluff as class skills, and can be any alignment. It pretty much meets all your requirements!
