Blue bow tie for 11

Alright, now im looking to get a bowtie like the one the 11th doctor wears in series 6, it looks almost like denim i think? I see one that looks pretty close here, Night on the Town
But if anyone has any other cheaper or more screen accurate ideas for this bowtie, please post it here! Im working toward getting the tweed and don't have much money to spare toward any other additions to my costume at the moment, so all help is appreciated!
