Hello, Welcome to Madmext! Thank you for your interest in our "Beige Adjustable Waist Striped Pocket Wide Leg Women's Trousers Mg2312" model. We would like to help you determine the most suitable size for you, considering the height (163 cm) and weight (63 kg) information you have given, as well as your hip structure. Under normal circumstances, size **M (Medium)** is suitable for these measurements. However, since you mentioned that your hips are a bit wide and you may want our trousers to look loose, you can also consider the **L (Large)** size. The **adjustable waist** feature of our product is a great advantage; this way, even if you prefer size L for your comfort, you can easily narrow and adjust the waist part according to your own measurement. The wide leg cut will also provide a very comfortable use in the hip area. * For a more flowy, relaxed, and draped look: **Size L** * For a slightly more fitted silhouette: **Size M** might be a better fit. We wish you pleasant shopping! Madmext Team
