seeing my glutes SMALLER in leggins, has it ever happened to you?

I know I have a fairly big and muscular booty (and I have been told that!), have been working out glutes and legs religiously for the past 2 years. To the point that quite literally leggins are actually unflattering on me, it feels like they are actually making my glutes look smaller which is the reason I feel better wearing sweatpants. Has it ever happened to you too? Is it only body dismorphia? IDK I just love the way I look with jeans or sweatpants, but somehow leggins that should be the most flattering are actually making me feel smaller than I am. (or than I think i am, lol, but again as I said, butt looks actually pretty good in normal clothes)
