The only purge I did when I started transitioning was getting rid of my “guy things”. I have never looked back.
I feel zero impulse to ever present as male again.
Now, I have culled my closet a few times to clear out stuff that didn’t fit me well or were early poor choices in style or color. But I don’t think that’s the same thing.
I did have some nice well worn button down guy shirts with great patterns that looked good on me en femme. I’ll confess that I regret getting rid of a few of them.
