I keep looking at the Wish Bowl sale... good deal on GND2, but I don't want to spend on clothing (although CP has a nice GND2 set by Karanta for 1.99 at the moment).

I have Morphing Clothes. That should allow me to add GND2 as a morph option to my V3 clothing, correct?

Technically, yes it should. 

Ah, the old "technically" fallback. ;)

Yeah, I suppose that the more radical the morph, the more the mileage varies with the results.... Still, I wouldn't think the mesh of GND2 is deformed THAT much.

It shouldn't.  Isn't GND2 based on Stephanie Petite who is loosely related to V3?

AFAIK, GND2 has no relation to SP, just a custom sculpt of V3 by Blackhearted (just like GND4 is to V4).

Yep, your right, just checked.  Getting back to your OP, the GND2 morphs applied to your V3 clothes should work just fine.  I can't imagine any foreseeable problems with the conversion at all based on some of my successes with the app.

Thanks. I sprung.

I've had Morphing Clothes almost since I began, but have only used it a couple times.

Believable,

Take a look thru the freestuff here as well there are a fair number of clothing fits for GND2.

Lyrra Madril also has a set of GND2 fit magnets [http://www.shop.cyclopsstudio.com/product.sc?productId=39&categoryId=4].  I've been thinking about picking them up since GND2 went on sale.
