What can I wear under this? More in caption.

Just thrifted this dress and have never worn anything like it before, so I’m not sure what kind of underwear to wear with it. The tie on the side is pretty high and will not hide a regular waist band. The fabric is flowy, and definitely will not hide panty seams. I’ve been looking at Skims, Huha, and other seamless options, but I think the wide waistbands would be visible where the hip tie is. Any suggestions on what to buy would be appreciated!
