I held a position in England for 2 years that required me to wear a shirt and tie everyday, and a lot of that time was spent outdoors. My tie was always blowing around and getting twisted up in the wind, so I was constantly fixing and straightening it. A friend passed on his knowledge of the "tie saver" trick, and it was life-changing.
This is as simple as re-using an older shirt that would have been thrown away anyway, to create a simple, but surprisingly effective tie strap. The best part is, nobody can see it. It just looks like you've consistently got a perfectly straight tie without any effort at all. I've seen these types of products sold 3 for $25, but you can make 3 "tie savers" from 1 old dress shirt, for free. This is a life hack I personally use every time I wear a tie. It's helped me tremendously, I recommend it, and I hope that by sharing it, it will help you as well.
