Jr Hunter
She was my first mandalorian, before that it was Pilot, Jedi, Stormtrooper, and since I have made a custom mando. It was a tad addictive to begin with though Im slowed down now. 
The other thing too, which i think is equally important is to actually like the character. Rav Bralor is also know as Vhonte Tervho Vhonte Tervho - Wookieepedia, the Star Wars Wiki Well, actually this is where it gets strange. In the books Vhonte and Rav are two different people, though when the Rav action figure was made, it looked like they used Vhonte as the model.
The reference drawings for Vhonte Tervho are draw by Tom Hodges Thomas Hodges - Wookieepedia, the Star Wars Wiki He is married to Terri Fontana-Hodges, for whom he named the character Vhonte Tervho (the first visual reference of a female Mandolorian)
So "Rav" was the first. One of the fun things I was able to do when we traveled over to America last year for C6 was to get Terry into my Rav Costume, fitting since the character was arguably named after her
You could go for your own style. The armor would accent you as a person and make you recognizable without having to take off your bucket
Welcome! There are a few Female Fetts or "Femme Fetts" as we call them around! Lady Fett is one of the more popular ones and has a Facebook page.
There is also a newer Femme Fett in the works and I believe her name is Danabanana and is in the UK.
The maker here known as Fettpride, or FP does make female fett armor and can be reached at Fettpride@fettpride.com. It's certainly not an extremely common costume...
