My brother's wedding

So, long story short. My brother asked me to be his best man, about two weeks after I came out to my wife. After I came out to the family i gave them the option pleanty of time to think about what they wanted to do. No pressure, it's there day and happy either way (originally they were worried that I would out shine the bride by dressing over the top, once they saw me fully and I explained the differences between being being transgender and what they saw on Drag race

I feel for your predicament, but in your place, I'd just tell him, look bridesmaid ok, best man, sorry not able to do that, not even a man here.

You don't want years later to make his wedding pictures 'awkward', "oh yeah, my best man was actually a woman".

Ah, may have not been clear. The wedding was last weekend! Lots of photos, with different combinations of people!

Yeah, I thought we had already had this discussion

Would love to see some pictures.
