My latest working experience was with a multibrand showroom in Paris where we hosted 5 different womenswear fashion brands. As account manager for these brands, I was responsible to source buyers for my assigned geographical territories which consisted of Scandinavia (Sweden, Norway, Denmark and Finland), Netherlands and the US. I sourced over 600 stores over the time of 2 weeks and I managed to get the buyer's details for 90% of the stores.
By benchmarking your brand together with similar childrenswear designers I would find the most appropriate boutiques for you to target. By calling the stores I would get the buyer's contact information. Please contact me to discuss further details such as minimum amount of boutiques etc.
Best regards,
