What our customers are saying
Customers say these French cut underwear are exceptionally soft and comfortable, with many praising the modal fabric's cotton-like feel. Users appreciate the generous coverage and find they stay in place well during activities. Many reviews mention the waistband being too tight, with several customers recommending sizing up for a better fit. Common feedback includes excellent absorbency for light protection and durability through washing. While most love the French cut style, some note the leg openings can ride up during sleep or movement. Reviews are mixed on the waistband fit, with some finding it creates unflattering bulges.

    Got the mystery pack. It's clearly the rejects, it's hideous. Don't do it.

    PERFECT FIT!

    These are my first leakproof so I decided to buy four pairs. I love the material and the wide waist band and as a bonus they are so comfortable to wear.

    Love the band and the material

    I bought the grey pair because I loved the colour and the band but didn't want the boxer style. I was hesitant because I do prefer a brief style since I am a larger shaped body. French cut is not my thing. I was right I'm not a fan of the cut but WOULD LOVE this material and waist in a brief style. I will wear these ones obviously but would buy 20 pairs of they were in a brief cut. Perfect absorbance and placement for me. I just need more of my tummy covered.

    Very comfortable

    I like these underwear (I have a large/round butt) so a lot of underwear slide inwards, but these have enough coverage to stay put. I would say it is a "generous" cut. I wear a small size.
