I have a couple redish one I'm quite fond of.

I don't think I own a white shirt.
Don't take this in jest when I say this, but is there any way to tell them you think they should make something that would fit you? Either as a one-off (does Margiela do one-offs?) or as a future product suggestion? Would they care since clearly you're an important customer to them?
If they do indeed do MTO, would it be prohibitively costly?
