Good basic underwear at a fair price
Color: Multicolor-6pack-01, Size: Small, Color: Multicolor-6pack-01, Size: Small
These are simple, comfortable everyday underwear with soft, cool-feeling material. The colors are basic but practical, and they fit my 11-year-old well without any complaints about comfort.
Overall, a good value for the price and a solid option for everyday wear.

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
