This is silly, but I've been going back and forth over Rogue, or Lowlife Ranger for my 4th character slot. (Other three are Spellblade Fighter, Cleric (still seeing which domain I like best), and Shock Arcanist Wizard.
I usually choose this character to be female and they wind up in leather armor. It bugs me that the male leather is black, cool and screams "I'm a bad ass" while the female leather is brown and just says "budget city guard".
However, today I stumbled across the first Breastplate armor that I've seen and I put it on my female, elven fighter (DEX-based) and wow... She's not some over-sexualized goddess in a chainmail bikini -- she's covered basically head to toe, so the armor looks like it'll actually protect her (shocking, eh?) -- but she still looks really good. Much better than the leather armor. I think the breastplate armor says "look all you want, but if you touch you're going to lose that hand".
So, strictly for aesthetic purposes, Lowlife Sylvan Elf Ranger just beat out any female Rogue simply because the Ranger can wear the breastplate.
And yes, I know the Rogue could wear it too if you take Sellsword background, but... I just kind of like Ranger more anyway and I'm looking for any excuse to use Ranger over Rogue. :)
Also, I wanted to say "great job" to the artist who did the female breastplate armor look. :) I've actually been really impressed by all of the "props" (weapons, armor, potions, gems, books, etc.). The female leather armor is the only one that I find a bit disappointing.
