I'm having a hard time getting photos that look like what I see in the mirror. I was hoping that maybe someone here can help!

I found some jeans on Amazon that illustrate the discrepancy.

This is what I think I look like, what I see in the mirror:

This is what my photos look like:

My hips/thighs look SO WIDE in photos, much wider than I think they do IRL. My photos make all my outfits look pretty bad, so much so that I don't want to post WIW! Everything looks out of proportion in my photos, with my bottom half so wide and squat. Is there anything I can do with the camera so that it reflects what I see in every single mirror in my house? I have two full-length mirrors, and three gigantic counter-height mirrors.

Or am I just delusional, and what I see in photos is what everyone else really sees?
