A wedding dress can determine how 'smoking' a bride looks on their big day – and now there are hundreds of dresses up for grabs starting as cheap as $9 to take that to a literal level.

Gregsons Auctioneers on Wednesday opened bidding on nearly 200 wedding dresses smoke-damaged in a fire next to a northern suburbs bridal shop in April.

Gregsons general manager Jack Gregson said each dress started at $9, far cheaper than their estimated values when new, which ranged from $500 to $2000.

Mr Gregson said despite the 'smoke damaged' description, the dresses were in great condition.
