There was an error when packing my order (in-stock) so I had to wait a month to receive it with weeks in between responses. I did get my items, the process was just slow. So I don’t recommend this item if you want to wear it to a specific event, instead this is more for planning in advance.
As for the item- I used the chart but went up from the size recommended and it was a good call. I typically am XL for underwear at other stores (TJ Maxx) and XL fit me in this case. I haven’t tried the bottoms for extended time but when I walked a bit it stayed on fine. I did wear the skirt out and it was comfortable both in and out of water. The green bow is only decorative, so you can’t adjust the tightness of the skirt or unwrap it. I would love that option, but in the end it was still cute and I got compliments.
