    Ultra Thin is accurate

    These briefs are truly ultra thin. I prefer the cotton ones so I know I have something on. If you prefer the commando feeling, try this design.

    Super Comfy

    I hate wearing bulky period underwear with annoying seams. These are super comfortable and I'll definitely be buying more pairs to wear on my lighter period days.

    First use - great!

    Got a couple of knix pairs to try out and they worked great. I wanted to be able to sleep with them while on my period and be comfortable, as it seems like I'm developing a pad allergy and I don't like sleeping with tampons. They were comfy and I didn't have any leaks! Will buy a couple more!

    Size up!

    I love Knix! The underwear is great, but when you order this shimmer three-pack, make sure you size up! They fit VERY small.

    Did I suddenly gain 10 lbs???

    I first ordered Knix bikini panties in a size small. Too big. I exchanged for XS and they fit perfectly. So when I ordered this three-pack, I didn't think twice and ordered XS. They're too small. Come on, Knix. Step up the product consistency please. (And other reviewers are right; the pea colour is awful).

    Far too small

    These shimmer sets are WAY too small, I’d suggest either sizing up or get the non shimmer sets. The fit of these is way off.
