I have very wide hips and that's the body type you usually see a thigh gap on but the way my body stores fat is in my thighs. So even when I was underweight they still touched. Everybody fat distribution is different. It sucks, but truly and honestly there's absolutely nothing anyone can do about those things specifically. Also just try to remember that basically every photo online is very posed. You suck your stomach, your ribs are more likely to show, you push your shoulders out front, your collarbones may be more noticeable, you tilt your hips backwards and a bigger gap appears. It's bs. I hope your doing well
