What would you pay for this? (taylor swift)?

I made a close (not exact) well made duplication of taylor swift's dress from her music video love story for an american girl doll. it is beautiful and very very similar to her dress in the video. The sleaves are the same the same basic design, lace up bodice, long flowing three layer train, gold material accents the front of the bodice and skirt( just like taylors) This took me about 6 hours. It is completely original and one of a kind, i made the pattern and the dress myself, so what would you be willing to pay for this item. (thinking about puting it on ebay but wondering if anyone would be willing to pay enough to make it worth the time I put into it.)
