Best Tokyo outlet mall for mens suits

Does anyone know the best outlet mall for mens suits and thats easy to get to by public transport from Tokyo?
Thanks

There's a place called Zen Mall in Shibuya that sells suits. It's close to the koban at the bottom of Spain Dori.

Have you been to Lalaport Toyosu?

They have lots of mens & womens clothes there. One of the stores says:

P. S. FA Reasonably priced business fashions for the working man and woman.

So that sounds like what you are looking for.

The map and location and store hours are on the website.

The best outletmall is "Gotemba", surely.

The next best might be "Karuizawa".
