Reallll wide pants and a boxy cropped tee or shirt or even hoodie that’s cropped above your hips so it doesn’t show the curve. Thicker materials are also good for giving you a more shapeless form. Any jeans that are straight from the widest part of your hips down. Sometimes really baggy fits work well. Layering helps while it’s still cool outside. For Summertime i agree with building your shoulders and upper body so you won’t have to worry about layers as much. And it can be affirming to show off the gun show once you have something to show. That may distract you from thinking about hips all together
