Now with pictures!
Step one: Get a binder and a pair of boobs. Boobs optional, but IDK what you’re doing here if you have none.
Step two: Strip to your shorts. Yeah, take the pants off too, you’ll see why pretty soon. Also, look, I’ve been working out!
Step 3: Turn your binder upside down. Make sure the front faces the front, and if it isn’t double-sided, turn it inside out.
Step 4: Step into it like you’d step into a skirt, ahem, I mean kilt. Get both feet in through the neck opening. Don’t worry about stretching it out, those things are durable as fuck.
By this point, you should have your upside-down binder stretched around your hips like a particularly constrictive 80s pencil skirt. Now for the magic.
Step 5: Grab your binder by the straps and pull it up over your torso. It should go easily, ‘cause it slides over itself. See pictures:
Finally step 6: Put your arms through the straps, and voila! Wasn’t that easy?
When I just got my binder, I did my fair share of struggling into it headfirst. My shoulders are kinda wide though, and it didn’t go too well. So I invented this method, and I invite my fellow transguys to switch over. It’s honestly so much easier, and it takes like five seconds.
