Ooo, I think you should get one, unless you don't have/own bracelets for a reason.
Every couple years I go through a stage where I think rings are the coolest thing ever, and find the perfect one, buy it, wear it for all of a day or two, remember how much I hate wearing rings, and never wear it again. Every time I go through this stage I remind myself about this cycle, and yet I convince myself that this time will be different. But it never is, and then I end up wishing I hadn't wasted my money.
So based on my experience, if you think this will be the beginning of your happy bracelet-wearing life, go for it! But if you've actually tried wearing bracelets before and they don't work for you, maybe you can find similar styles in a type of jewelry you know you will wear.
