My solution was a tie that had two pockets sewn on to its back. I chose this solution because it was appropriate and fashionable, and solved the problem of the glasses, while also addressing other important issues, such as a place for some sort of payment for his date, the fact that he doesn't actually have outer ears, and the fact that moles are very oddly-limbed creatures. This means that legs and arms aren't always going to be able to be be easily reached by own another. I also chose it because it would allow his glasses to be more protected that if they were located on him in other regions.
