Yes, Drow. Why Drow? Well...
Defensive Straps [Racial]
Prerequisites:Drow
Benefit: You can wear scraps that can be enchanted as magic armor without counting as armored. The scraps must be made from exotic materials or monster hides worth at least 300 GP.
Excellent! (Deadly Beauty is also useful for thematic reasons). Let's go with Swordsage, seeing as that gives us the unarmoured thing. Now, let's say that there's this exotic material that shall henceforth be referred to as life fibres, and give them a +1 enchantment.
Our next step: Weapons of Legacy! Misleadingly, these can also be shields. Or armour. Or random magical items. Really, all we need here is our +1 bonus. So, we might as well take the Champion of Legacy class (from what I recall, we lose just two levels of progression--still get to keep the 9th level maneuvers). Using our scantily-clad drow, we found a legacy.
So, what does this mean? Well, we obviously need our outfit intelligent to some degree. We can have it give us enhancement bonuses to stats. There's a selection of SLA's X times per day (a reason to pick up that class is we can use them more--it also has UMD as a class skill), including Fly. With a willing DM, you could probably get a better version of the flight thing (that does not for some reason demand holding the thing above your head).
And, of course, you can increase its enhancement bonus or other effects.
