Vivienne Westwood London during the Nana collab

Hi everyone!! Huge fan of Nana and VW and was so excited to hear about the collab. I have a trip to visit London November 12-17th planned for half a year now and thought it would be so fun to visit the VW Store while visiting but now due to the Nana collab drop on the 13th I’m wondering, will it be hell on earth? It was never my intention to visit my first designer store during the launch of such an iconic drop. I am a huge fan of both Nana and VW so I was excited at the idea of stumbling into seeing the collab in person but this would be my first ever time visiting a designer, certainly never during the drop off a big collab. I definitely could only spare a few hours in my short trip to visit the store. Would anyone with more experience know what I should anticipate/if it might not be something I can fit into my schedule any longer given that new drops potentially cause long lines?
