Skinny jeans fall down but waist is correct size. How d Sewing Machines Parts and Sales in Los Angeles

So I have various brands of skinny jeans. Some of them stay on just fine, and some of them fall down as I walk. Is there a way to fix this?

When googling, all advice says to make the waist band smaller. If I did that, the waist band would be too small. Also, I have other pairs of skinny jeans, the waist band is not too tight, and they don’t fall down. For me, the waist band being tight does not hold the pants up at all, and if it did, I wouldn’t buy those pants because I find that uncomfortable and unattractive (muffin-top).

My current guess is that the hip/thigh of the pant isn’t tight enough, but the lower leg is, making the pants pull down when my legs bend at the knee while walking.

Any advice would be much appreciated!
