Tiny problems

Ok so im like kinda small, not as in heighg but like size ig?

And its such a pain😖 cuz skirts are usually too big and even the small is kinda big!! And i like my skirts tiny! So then it hangs off me and the skirt gets long!! And then i have to pin it so it actually looks nice but anytime i move the pins pop off!!

Im struggling UmU :(
