The Aila medieval blouse has a generally loose fit, but the lacing at the waist and underarms gives it a close, figure-hugging silhouette. To determine the correct size, you can use the following chest measurements as a guide: S (88 cm), M (96 cm), L (104 cm), XL (116 cm), and XXL (128 cm). If you are between two sizes, we recommend choosing the larger size.
