Just the title.
Good fashion combination for girls?
The Scale line with the Dragon Scale Set and possibly the Radiant Silvermail.
One of my female knights wears Angelic Raiment (since it goes well with my personal color) and Spiral Tailed Helm.
The other one wears Spiral Flak jacket + Stranger hat decorated with a plume (which I consider to be a ponytail).
Both of them have the Almond Eyes, which are the "girly" eyes.
Also, have a look at the armor for Gunners (Gunslinger and its higher star versions) and at the Magic Cloak and its upgrades. Those look rather feminime, too :)
And frankly, pretty much all of the Proto armors look feminime to me too(I guess it's the "chestplate", the armors look like they have boobs), so if you like one of those... :)
And oh, let's not forget the Wolver line coats... Combined with the right helmet, those can look somewhat girly, too.
The tailed helm, or the emberbreak helm
The angelic line.
The gunslinger hats
These look really good especially with flowers and glasses.
