Why buy an expensive umbrella?

I'm curious, why would someone invest in an expensive umbrella? Isn't the purpose of an umbrella simply to keep you dry during rain? Are there specific features or benefits that come with a pricier model that make it worth the extra cost? Perhaps it's made with higher-quality materials that last longer, or it has innovative design elements that enhance usability. I'd like to understand the rationale behind spending more on an umbrella and what value it brings to the user.
