A simple reason I like to try on clothes in-store or in-person (or trying out shoes in-person) is because you never really know whether you like or something or not, until you try it out, test it for yourself, on your own body, etc.

This applies to ‘test driving’ a car, ‘test driving’ a home (ideally, you could experiment and test living in a certain house/condo/apartment for a week or two or a month before signing a year-long lease), testing out a camera (in praise of ordering cameras online on Amazon and if you don’t like it, just return it). Same also goes with iPhones, iPads, Laptops, Apple devices, etc (buy it, and test it, and if you don’t like it, return it within 14 days).
