All for Leifang of course..
DOA4: C2 (white Chinese dress), long hair, pink glasses
DOA5: << my profile pic << C3 (school uni, with jean jacket) long hair, no glasses (its a shame she only has red now)
DOA5U I still dabble around with C3, but C11 (panda) is there for fun. I use C15 (black leather vest), long hair, no glasses - for those no-nonsense matches. It was an old DOAU fave of mine, and now they made it meshless, so it gives me more of a serious/mature feel.
I also like her in glasses, but feel like the red doesn't fit with hardly any of her outfits, except Christmas Lei (C18). I think Lei rocks the santa outfit better than any of the rest of the cast with red glasses and long hair.
On a side note, if you ever see me with default braids Lei, then I've surely made a mistake forgotten to press LB. Ever since I found out she had the long hair option, I've never even tried to go back.
