Not a confident fit.
Color: Multicolor-6pack-03, Size: X-Large, Color: Multicolor-6pack-03, Size: X-Large
Love the material and the colors are fun. The sizes might be a little too big. I haven’t tried them yet but I just opened the box. I thought I ordered an XL? Not 3xl (is what the box reads?)

No wedgies or pinching.
Color: Multicolor-6pack-01, Size: Large
Finally panties that deliver without causing wedgies or a muffin top. The full coverage design stays in place all day without pinching around your legs & waistband is very thin to give you a smooth silhouette

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.
