    Love this fabric

    Incredibly soft, breathable, and comfy. Star style has the perfect leg length for more petite frames. I actually purchased an XS (couldn't select this option for my review)- I'm 4'10", 80lbs. If XXS were available, fit world have been ideal but XS suffices.

    Perfect style for petite bodies

    This is my first pair of Woxers and I think they may now be my favorite underwear. The weight of the material is perfect for just the slightest support while maintaining excellent breathability. I love the wide waist band. I have skinny legs and had problems with the boy short style holes being too large but the Star cut does the trick and best thing… No wedgies!

    I purchased a size XS (this wasn't an option I could select when submitting my review).

    The STAR style is a superstar!

    This is my first ever pair of Woxers and I LOVE THEM! I'm usually a skeptic of non-cotton underwear but these were softer than cotton and very breathable. The "Star" style was perfect for my petite frame/skinny legs (the leg holes on the boy short style were a tad big). I love the non-rolling wide waist band. The fabric is the perfect thickness for providing a little support without uncomfortable pressure. 3 stars for Star! ⭐️⭐️⭐️

    I ordered a size XS (I had to select S since XS wasn't a selection option when I wrote this review)
