Forget the ironing board. Your new best friend is a steamer or even just the steam from your shower. Heat is fine, but direct pressure is the problem.
Think of it like this: a gown is a delicate cloud, and an iron is a heavy foot. You want to give it a gentle hug, not a stomp. The steam relaxes the fibers without melting them into a crispy mess.
What About the Cap?
The mortarboard is a whole different beast. That flat top is often made of stiff cardboard or plastic. Do not iron the top of the cap. You will crush it, deform it, or set it on fire—none of which look good in a family photo.
If your cap is bent, try putting it under a heavy book for a few hours. Or, just embrace the slight curve. Honestly, it kind of makes you look like a cool graduate who doesn’t follow rules.
