Reserved a time in the morning to be dressed in my own yukata. It was quite busy with other customers when I arrived, so I do recommend booking a time beforehand, especially if you have other commitments.
The staff were incredibly helpful, polite, and professional. They were very accommodating in letting me bring my own yukata and dressed me in it. They even let me borrow a few accessories I needed! Any language barrier issues could be resolved through a translation app, so there weren't any problems with communication.
They do charge a little extra than the standard yukata rental plan if you bring your own, but I didn't mind paying since it was very important to me to wear my own. I couldn't find an option for a 'bring your own' plan when booking on the site, so I chose the standard yukata plan. I just paid the extra at the shop.
Their Kenrokuen location is right next to the garden, so it's extremely convenient if you want to take photos there. Had a great experience overall with the shop and would definitely recommend if you're doing a shoot at Kenrokuen. Thank you so much!
