I think you come closest Elizabeth with "seamstressly" - easy to read, though difficult to say. Interesting that "housewifely" uses the adverbial -ly formation. (Are there other examples of adjectival formations that do this? I can think of "likely")

Good Dr Bill suggests via PM using an eponym from a famous couturier(e) but I think that runs into connotations of haute-ness again.

Thanks all - if this board doesn't come up with the perfect word, it don't exist!
