If you like to work with Milena (who is great-looking, like everything I've ever gotten from Maira), look for clothing that boasts of having the V2 morphs -- fortunately, more and more people are including them. As for adapting regular Vicki-wear, like the cocktail dresses, you can see if the individual part morphs will help you; I don't know what they have. If they don't have V2-like morphs, though, your best bet is probably The Tailor. I have always heard great things about The Tailor, and if it works as promised it's obviously worth the price. In fact, I've even bought it and just haven't used it yet -- but because I haven't, I'm loath to say it will definitely work and that you must have it.

Maybe I'll check it out for you, not on the Cocktail dresses, which I don't own, but some other Vicki-1 specific dress.

Meanwhile, don't despair that you have no clothes for Milena. If you have the Morphing Vicki Clothes, you have a lot more than perhaps you realize. The dress (and several of the other articles) has a number of different material zones which can be turned transparent or visible in the Render Materials window; this fact, combined with the Length morphs on the Hip and Thigh and sections, makes it possible to create a whole heap of different dresses in a few seconds apiece, of which I will picture just three:

(There's a snappy club/cocktail dress for you on the left.) I used V2 instead of Milena to save time on conforming, but I'm sure all these conform. The longer skirt lengths will only take certain poses, but that's true of a lot of long-dress meshes that you haven't already paid for. Make all the material groups of the dress opaque and your model is covered from chin to wrist and as far down as you morph the length: it follows that with your own custom-made transparency map, you can scoop down the front, lower the backline, add a slit to the skirt, etc. Bump maps can put pleats in the skirt. None of this, fortunately, requires any real talent -- I say this from personal knowledge. So you can actually make quite a wardrobe for Milena from what you've already got. (And if you make something really nice, and charge low enough, you can sell it on Renderosity!)
