very cool indeed. we need local 3D scanners in communities so people can go get scanned and send that scan to shapeways and get their bespoke clothing. These items by continuum are very promising (mainly the programing behind them- thanks for sharing that info!).
What's being sold right now isn't really bespoke, you just choose between sizes like you would for a normal bikini in a store, so I don't really see the advantage of this being 3D printed in polyamide versus traditional mfg & materials.
That being said I'm happy Continuum has gone this far and worked w/ shapeways to make it available. It shows the potential future, which is awesome. And it will make some headlines, turn some heads (especially guys), & bring attention to the industry & traffic to shapeways which is great! I doubt it will be that successful in terms of sales, but hopefully this doesn't deter Continuum from a very interesting future.
for me the only tight fitting items on me are my shoes, so bespoke sandals would be seriously interesting.... especially with a custom footbed based on a scan of my foot... hmm someone should do that.
