She's wearing Mint on Card glass eyes in dark purple (probably 20mm, though these might be 18mm), her original lingerie, and a hoodie set by Nine9Style, which is currently sold out (but you can still get it from some dealers, like Peak's Woods).
Personally, I believe the sign of an excellent face-up artist is that you can feel comfortable sending them a head that needs a new look with little to no instructions, and ask the artist to do whatever strikes his or her fancy. Leah Lilly did just that for Megu.
You can see Megu's original look below--which is actually her original hand-painted look from Volks. What a difference! (She is a standard Volks model SD10 from 2004--quite old in BJD terms.)
