I bought some ties when I was just starting to figure myself out. It was an awesome feeling-- I'd just wander around the house wearing a shirt and tie with no-one watching no one watching. My area is so casual that only a few very old-school people wear ties to work, so I'd look pretty odd doing it even if I was presenting as male. I wore a three-piece men's suit to a friend's wedding, complete with tie and pocket square. (One of the brides was in a suit and tie, too, though I'm pretty sure she just identifies as a lesbian.)
I hadn't consciously thought of wearing a tie as a way to counteract dysphoria. But, you know? That's totally what it is for me, too.
