Beauty contest officials chose a model from Stoke-on-Trent to represent Birmingham because they could not find anyone pretty enough from the city.
Sophie Wilson has never lived in Birmingham
Miss Great Britain organisers picked Sophie Wilson to represent the city in a heat despite her only connection being an ex-boyfriend who lived there.
The 18-year-old IT student said she thought it was unfair on Birmingham's beauties.
The competition was later won by Rachael Tennant, from Aberdeen.
Miss Wilson said: "When they said there wasn't that many pretty girls in Birmingham I didn't actually believe in that.
"There are obviously going to be absolutely gorgeous girls about but I just think they weren't auditioned."
Tracie Bedwood, of Birmingham model agency Adage Models, said she could not believe the decision.
She said: "If it's someone representing Birmingham then they should be from Birmingham.
"There are lots of beautiful girls in the city and I know because we've got lots of them on our books."
A spokesman for Miss Great Britain said: "We were desperately looking for a Miss GB entrant from Birmingham but in truth, there was no-one suitable who entered.
"We look forward to more entering next year."
