Is the item conforming or dynamic? If it is a conforming item your only choices might be using magnets (might be a bit complicated) or using the "Tailor", which lets you transfer morphs from the character to a clothing item designed for that character, you might be able to find a trial copy of this application in the freestuff section. As far as dynamic clothing goes as I understand it should take to the bends and shape of the character.

Ask me a question, and I'll give you an answer.
