Just too lose on waist

It’s a really nice, flowy material. Very comfy. It weighs down very slightly because of the weight of scrunch of material, but it’s not an issue. I followed fashion nova’s overall size guide and thought I match better with the size medium. For context, I’m about 5’10 feet, bust = 91cm, waist =69cm, and hip= 87cm. It fits well, the straps aren’t adjustable but the size i chose ensures it doesn’t fall off my shoulder. The ties makes it very flattering. Under the ties looks a bit loose so i could’ve possibly gotten away with a size small but i personally don’t think i’d wanna take that risk. Plus it looks like it’s apart of scrunch design so once again, no issue.
