How much comission doesn the consultant make on a wedding dress?

none - the bridal shop and the wedding consultant are two completely separate wedding vendors. if the consultant has a special relationship with vendors that they've worked with many times before for example a stationer, calligrapher, photographer or baker-whoever; then they may have made an arrangement between themselves ex. the bridal shop reccommends the consultant that they have an arrangement with to brides who come in their shop and the planner reccommends their clients to that particular dress shop. in that instance- both parties may receive kickbacks from each other (a percentage of the profit received from what the bride or whoever the customer is paid them) but that's not considered commission because the planner doesnt work for the dress shop or sell dresses for a living- the employee who sells the dress may get a comission which is totally unconnected to the arrangement that the dress shop owner and consuktant may have.
