Smooth panties for comfort

Inferior Product!!

I recently purchased four pair of Wacoal briefs. I’ve worn this style of brief for many years. The fabric on the briefs I received stretches, and is so slippery that they don’t stay in place. I’m 5’1”, 107 lbs, I’m 91, and wear a panty liner, the liner has a sticky back; but will NOT stick to the brief, therefore, stay in place!

Not sure about this

I wear other Wacoal panties and all of them fits very well but this one is very off. The crotch is so narrow and the leg area is so tight. The waist is very loose. Just very off and disappointed - not cheap panty but I have to throw it out

Smooth undies

I received these about two weeks ago. I love the way they feel and not show under my pants. I have purchased these briefs many times and hold up nice in cold water wash.

No cotton crotch - liners won’t stick

Panty liners will not stick to these. That’s a dealbreaker for me unfortunately did not find out until after I purchased three pairs.

Seamless Brief

Not what I was expecting. It felt more like I had on spandex. I thought fit too tight and of course, felt like it was riding up all the time. This just wasn't for me.
