Which size should I choose?

Each size is drafted on its own. Open the size guide above: these are the dress's own measurements, so compare them with a dress you already wear. Between two sizes, take the larger one. Wrong size after all? Email help@lauven.shop with your order number and the size you need — our team will arrange the exchange.

Can I cancel my order?
