Seconding the leather-rim idea, especially for formal wear. The leather gives a clean edge in photos. Ask for a size chart and, if possible, a photos of the exact piece on a head so you know how tall the dome is. Customer service at the shop I used was helpful about matching rim color to shoe belt tones.

Hold up, you ate that stir-fry after it hit the floor? I'm shocked you just rinsed it and went for it. My kitchen floor has seen things I don't even want to think about, like dropped raw chicken juice from last week. Germs are no joke, and a quick rinse won't fix that. You're braver than I am, or maybe just really committed to that budget life. Still, I'd draw the line at eating floor food, fitness prep or not.

Honestly that view seems way too strict to me. I did commercial diving in Alaska for years and we never used drysuits, just really good wetsuits with hoods and gloves. Your body gets used to the cold if you dive in it regularly, and you keep way more freedom of movement. Calling them key for safety feels like gear fear talking, not real experience. Proper training and knowing your limits matter way more than what suit you're wearing.
