Hello, First of all, thank you for your interest in Madmext and for choosing our "Ecru Floral Patterned Vintage Chiffon Maxi Skirt MG2776" model. According to your height and weight information (175 cm, 65 kg), size **M (Medium)** will normally be suitable for you so that the skirt fits perfectly on your waist. However, since you are 175 cm tall and want the skirt not to look short from the bottom, but to give a full flow and long maxi length look, you can also choose **L (Large)** size if you wish. Our chiffon skirt will look incredibly chic on you, regardless of your size, thanks to its flowing, vintage-inspired design and draped cut. In order to make the most accurate decision, we recommend that you compare the "length" measurement in the size chart on the product page with a similar skirt you enjoy using at home. We wish you pleasant shopping and hope you have a wonderful day. Best regards, Madmext Team
