Yes, I do this a lot with dress pants and dress shorts - I only wear Docker's brand for both, and I will buy up multiple of the same style and the same colors since they only come in like 4 colors to begin with. But it's inevitable that I will have a pen leak, or spill some wine or get a cigarette burn in one of them, so I like to have backups ready when I need to toss out a pair for whatever reason. Also, depending on where I am travelling I will carry multiple of the same style and color in case of an accident - so as not to draw too much attention to the fact that I had to change. I've been meaning to bring them to work with me too, again in case of an accident, you never know. One time I was at work and went to pull a loose string out of the shoulder of my shirt, and accidentally took my whole sleeve off, lol. Thankfully I lived a couple miles from work, so I snuck out and went home and changed. I taped the sleeve back to the shirt, and just prayed I could make it to the parking lot without it falling off and anyone noticing.
