Larger sized clothing

I thought it may good a good place to ask. Is there any sites or ways you can get your hands on Yonex/Victor large clothing?
I really love Victor products over any other brand, but their clothing fits so much smaller. I currently fit most Yonex XL clothing. A Victor XL feels like a Yonex M/L.
I am 6’4 260lbs. Not a huge belly, just a wide shouldered larger guy.
Seems like Victor and Yonex have 2xl/3xl in their sizing guides but you can’t find them anywhere?
Suggestions or links?
Appreciate any feedback.
