    New version does not fit

    Everything I’ve ordered in the past is no longer available. It seems most thing are for teens or heavy flow. The only pant ly that a plus size senior can wear is this high rise. The old high rise fit just fine but this new version does not.

    Love these!!

    I love the selection of colors and matching bras available. They may be a Lil pricey, but so worth it. I now have several pair. I love them and the comfort is so good too! It was also nice to get them in a timely manner as well.

    High rise underwear

    Terrible fabric! Plastic feel against the skin and uncomfortable between the legs.

    Good quality

    I have only used these once so I am not sure how they will hold up over time yet! They washed out really well. I washed them in a garment bag. They were very comfortable over all.

    The only thing I did not like was I keep myself shaved and the underwear irritated the sides of my private area.
