Where to get traditional happi in Tokyo?

Hi,

I am in a urgent to know where can i buy affordable traditional happi in tokyo? I need to buy that for some traditional performance. I will be going Japan on the 14 june. I will be staying at Asakusa area.

If there is second-hand and in good condition, i may consider to check it out there. But please note that i will need about 10 pieces.

It will be such a big THANKS for the quick reply before i fly. Thank you so much for reading!

There are quite a few stores around Sensoji that carry traditional style hapi. I recall a few shops that had some really nice ones but they weren't particularly cheap.

Or are you looking for something more generic like these:
