How common is body checking?

30F and this term refers to women taking full body pics/videos of themselves to see what they look like right? I’ve done this for years, it initially started when I was on my weight loss journey. I’ve maintained the weight loss for almost 10 yrs, 70+ lbs down and still wear a U.S. women’s size 10. Unsure if this is a case of the typical body image issues or the trending term Body Dysmorphia. To this day, I just feel like I look big compared to the average woman. 5’7 and I know angles/certain outfits trigger these insecurities, I hate wearing shorts. On top of being pear shaped, I always feel more confident in a flattering pair of jeans or jumpsuit/longer dress. I’m just always worried about what I look like..
