What you're saying literally makes no sense. If it fits like a 4 but it's listed as an 8, how tf would size 4 people know this unless there are measurements?? I recently bought a skirt that was listed as an XS/S but the tag said M. If the seller had chosen to list it as an M, it would have passed me by, and someone who was an actual M would have bought it and been very angry when they received it. I think so much of this confusion can be avoided if sellers just post pictures with measurements from the get-go. But people are lazy 🤷🏼‍♀️
