Since Wardrobe Wizard is gone. Are there any alternatives?

Quiet simple, If you own Poser 11 pro from Smith micro or a Prior version like Poser 2014 just copy the needed python to the Poser 11 Bondware version and it should be working again. Else try asking someone you know to send you the files. Actually it should of remained a option in Poser 11as it was a part of it when originally purchased. Have no Idea why Bondware removed this option with many others.

PhilC has retired, and is no longer supporting Wardrobe Wizard. While you can still use it in Poser 11 and below if you have the files, he's not making new modules to support new figures like La Femme or Dawn 2.

Crossdresser by EvilInnocence is probably the best replacement.

Agreed.  Crossdresser works best ATM.  I have used it to transform various types of clothing for different models both old and current.  There is always the Fitting Room but there is a hit-or-miss with the process depending on the clothing type.

I'm with hborre. Crossdresser by Evil Innocence works great. I bought licenses for all the characters, since it cost less than buying just the character licenses I wanted individually. I love Wardrobe Wizard, too, but I'm using Poser 12 now.

I would use a combination of fitting room and morph brush.

Although the combination of the Fitting Room and Morph Brush can give a superior result, there is a steep learning curve to get the outfit to fit just right.  If you're looking for something straight out of the box with minimal adjustment and fuss then my choices would be Crossdresser and the Fitting Room.  Morph brush for cosmetic correction.  Don't forget Morphing Clothes, if still available, but that program seems to have been replaced with the copy morphs in Poser.

Of course, it also depends on budget. While Fitting room and Morph Brush are included with the Poser program, Crossdresser's licenses for each individual figure can add up quick. 

How true but you would deal the same situation with Wardrobe Wizard licensing.  Depending on the models you own, you could incorporate Pre-Fitter into a workflow that works well with the Fitting Room and the Morph Brush.  The app and morph packages are not free though but it does conveniently convert easily to get a near-perfect fit in minutes.

Just for comparison: when I added up the license costs I would need for Crossdresser to have a conversion library for my most often used figures, it was in the 60-70 USD range. I can't afford that right now, so kitbash via  Fitting room or using WW from older Poser install it is.
