The annual San Diego cake show is in a couple months, so I'm trying to plan ahead. I had an idea for a wedding cake dress, but it's a little different than ones I've seen in the galleries. Most of those are the ball gown style with a small bodice. Being for a cake show and made from dummies, I figure why not go BIG.
Here's a drawing of it:
You can probably tell from the picture, but the blue outline is the cake, while the horizontal lines separate the dummy tiers.
I'm worried that the small diameter - especially the waist - makes it a little unrealistic to do in actual cake (although I have seen some pretty unrealistic 3D cakes compete and win!), but they are in proportion. It's all scaled down from ~ size 6.
What do you guys think? Thanks in advance! 
The bottom of the skirt is supposed to be puffy looking, sort of like this dress: http://media.theknot.com/ImageStage/Objects/0031/0054933/larger_image.jpg
To do that I was going to do either fondant doubled over with an air pocket (like a bow is made) or several ruffled layers, depending on the final look I decide on.
Thanks for the reply, by the way. It's nice to hear that it doesn't look too crazy from someone who actually knows what they're doing!

oh...
yeah
hmmmm
well now
that is an "interesting" dress.
some how fashion like this is just lost on a guy!
LOL 
I think your design is fantastic! I don't think it's unrealistic either...quite doable just as you have illustrated. I can NOT wait to see the finished piece!
ETA:
4" waist? Is that after carving? Will the sizes used be considering the side view carving as well. 'Cause that side view may not give enough substance to account for the in then out curve from the shoulder to the waist then the waist to the buttocks...( I don't think doing it in styrofoam will pose that big of a structural problem but duplicating the tapering of the small of the back may pose a problem in cake...unless, when duplicating it, you opt to do the upper portion in another medium)
LOL! I'm not a big fan of the dress I linked to either, but it was the first one that came up on Google image search that had a poofy bottom.

Yes, the 4" is after carving. I have a side view drawing made as well (just in pencil, I don't have it on the computer yet) and there is a center line the whole way until the the neck of the dress form. Considering how small the actual neck will be, I don't think that will be an issue. I completely agree though, if it was real cake I would definitely do the top in RKT and just mold it around the support pole.
I suppose I should start early just in case the carving doesn't work. That will at least give myself enough time to try again or come up with another design! 
Thanks vickymacd!
Okay, I'm not a genius cake maker, but I DO have an almost 3 year old and an almost 1 1/2 year old who are both giant CAPITAL XX Chromosomes... so when I saw your drawing, I automatically thought.... "That's Cinderella's first dress calmed down!" -You know, the one the mice and birdies made? -gonna go check your link Anyway, maybe it will be another point of reference? If nothing else, you have my best wishes and prayers!
