Karen and Ian had a talk with me, and mentioned during their talk that Primark wasn't a brand and they were unethical and may not be appropriate for the collaboration with the museum , they also mentioned they liked the idea of collaboration of museum and they went through few brands for me to have a look at to replace primark,  after going home i looked at different kids clothing and fast fashion companies i decided to H&M as the brand to collaborate with museum.
below is a brief line overview of the company

First store opens
