What is the proper way to wear shirt garters?

I recently bought shirt garters to tuck my shirt into my skirt, I know how to put them on the shirt and how to wear them, my main question is this: Is it possible to put the garters on so that I can still use the restroom? It took my 20 minutes to put them on, and I couldn’t pee for like 8 hours because I didn’t have time to take them all off and put them back on again. The clips are sort of weird, and are hard to put on without the shirt slipping out of the clip and bunch of times, which is why it took me so long to put them on.
