can anyone help me find a dress similar to this?? i’ve been looking for ages but everything i find is very low quality, cheap fabric, but most of all they never have the form! i really want something flattering like this so it holds shape so i can wear it under dresses as well as by itself. any help or any similar items are appreciated!

the slits and strings are not necessary! i can cut and thread those myself :p

i also have a very low budget, but any find is appreciated, i can always save up!
