Instead of buying the same dress for multiple figures, you should really check out Wardrobe Wizard by PhilC and Kamilche.  It's available at PhilC's site    http://www.philc.net/WardrobeWizard.htm
     and at Content Paradise. It's currently on sale at Content Paradise for under $48.00 which is a savings of $12.00

There is a table listing all of the supported figures. With WW you can convert clothing between any of those listed figures with a click of a button or two. It's super easy.  And while you may think  it is a lot of money to pay for a poser item/program, it really isn't. WW is an investment and will save you money because you can use one outfit for all of your WW supported figures. Plus it saves on hard drive space because you don't have to have an outfit for each figure saved. Simply analyze it once and then just put the outfit on whatever figure you want to use it on and click one button and it is converted to fit that figure.  Very easy.

Here is a post I made telling someone else the merits of the program:

While most of the figures are supported with the base program, some aren't.  V4 is one that you have to buy a $5.00 add on file for in order to use her with Wardrobe Wizard. That extra file is available at Phil's site.

It's a great program, and the best thing I've ever bought for Poser. It's saved me a ton of money because I can use all of my figures' wardrobes with each other with just a few clicks of a button. And I no longer have problems fitting clothing to morphed up figures because I analyze the clothing first, then inject the morphs to the figure and then fit the clothing to the figure using WW.

WW is the first thing I install after reinstalling Poser.  I can't imagine every going back to using Poser without WW. In fact earlier this year I bought a new computer and realized I hadn't saved my key for WW and wrote to Phil in a panic asking him for a replacement key.

This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
