While I'm at it:
I have a NS 2011 Soom SuperGem that matches Migi and LM really well as well as a 2012 Soom SUperGem head that is the same color as the 2011 resin.
I also have a 2011 Luts Delf girl who is a significant shade darker...I hope this makes sense, the color between her and my Migidoll/LM hybrid are close but she is a shade or two darker. Wouldn't be a bad match but the others are better.
My friend has a Leekeworld head from 2011, it's actually pinker than Migi, also would not be a bad match but Soom and LittleMonica are closer.
And those are all the companies I have XD I recomend LM for a normal 63cm boy body for your Migi heads, I have also heard that Souldoll and Iplehouse are matches but that if you put a Migi head on an IH SID body you definately need to mod the neck for it to fit.
As far as girl bodies go, I just ordered a Luts SDF Noelia so I'll let you guys know if the new Type 2 SDF body can work with Migi, I really hope so!
//on a side note, I remember one of my friends saying Supia is an alright match for Migi but it's better once the resin has mellowed out after awhile, I think she said it was like an 80% match
