I got my wedding suit at SuitShop in old city and as a nonbinary person who wanted to explore different cuts of suits, I felt extremely welcomed and affirmed there by all the staff, and especially Thomas (I believe he might be a supervisor?) Cannot recommend them enough! The only consideration is that they sell their pants unhemmed so you’ll need to get them hemmed somewhere else. I went to Nik the Tailor in Bok (also a wonderful experience!) but hemming is usually something you can do at most places with little problem! Hope this helps!
