Can hips be changed?

ummm...depends on your bone structure I suppose. If you don't have much covering them, then I would say your hips are just wider and it's the way you're built.

That doesn't sound super wide at all? Thats about my hip measurements.... And you have a tiny waist! Embrace your curviness!

As people have mentioned it depends at what weight you're at now, how much fat you currently have, and genetics. Some people are just going to have wider hips than others no matter how much weight and/or fat is lost.

In addition as some one also mentioned odd number sizes (in America at least) are typically sized smaller than even number sizes. Odd numbers are juniors sizes, while even numbers are misses. That means junior sizes are cut and sized to fit teenage girls while even sizes are cut and fitted to be worn by an adult woman.

Also sizes from store and brand can differ greatly a size 4 from H&M, Old Navy, American Eagle, and Express will each fit someone differently. It means nothing against you it's just how they make their clothes. Try not to worry too much about size and worry more about if it actually fits and looks good on you. I work retail and it's always frustrating to see people trying to squeeze into something because they're always x size and does not look flattering but if they went up a size or two it would look awesome.
