Hi Agatha, thank you for taking the time to leave your feedback! Yes, we understand the issue with sizing, and it is a prevalent issue with such a business model like ours. Which is why we provide, as much as we can, the measurements - even if the piece comes with the size tag. As the pieces are pre-loved, there might be some minor alterations or change in fit due to wear. Nonetheless, we hear you, and this is something we're working on improving. So, hopefully, we'll sort those out soon!
