It’s not that I enjoy returning clothes. It’s that it’s more enjoyable than doing the brick and mortar retail fitting room thing. At multiple stores the logistical burden is too heavy.
Retail: I like this shirt on rack, try on two sizes, wait one size I need is sold out. End up settling for another item that I like and has my size in store. Might be third or forth option. I might just say forget it and leave empty handed.
Online: I kind of like this shirt, I buy 2 sizes I think might work, try them on when they arrive in my house on my time, if I actually like the fabric/look in person and I’ve identified the size works, I keep one of them and return the other. If I ended up disliking the fabric or something entirely that I couldn’t tell from product pictures I return both.
That said, the logistical issues of browsing/shopping online are significant too. I tend to be somewhat brand/store loyal so that’s how I deal with it.
