I noticed that my little sister recently purchased a new, really cute dress, and upon closer inspection, I saw that it was an XL. My little sister is tall and lanky - she tends to buy larger sizes not for the width, but for the length, otherwise dresses would end at her crotch. I, on the other hand, am tall and wide, so larger sizes work with my body for both length and width. I knew the dress would fit me if I tried it on, because I’ve bought clothes from the name of the brand that made the dress, and they always make their merchandise with stretchier, flow-y fabric. The dress has a zipper in the back that goes from the middle of the back all the way to the base of the neck, so I asked my mom to help me zip it up. Her response? “It’s not going to fit. You’re going to break it or rip it.” I asked her to please just try and she refused to do so because she thought the dress would tear. It really hurt me that she was so unwilling to even try to help me zip it up, so instead, I took the dress off, zipped it up myself, and squirmed my way into it, sans help from my mother. Lo and behold, the dress fit absolutely fine, and even looked pretty cute on me. I showed my mom, and her reaction was, “I think you need to take that off. You’re going to split it in half!” I proved to her that I could fit in and rock the dress, but apparently that wasn’t enough to convince her that I would stay contained in the fabric. Thin privilege is not having your own mother think you can’t share/wear clothes, even when you present her with in-your-face evidence that she’s wrong.
