Lovely look and feel.

Yes, I recommend this

Love these! Fit very well. I’m not sure I’d wear these alone, especially on heavy days, but they offer extra protection against leaks, particularly over night. Flattering fit and the most attractive looking period pants I’ve seen so far.

Great comfortable underwear, felt safe and secure

Yes, I recommend this

I bought these for my miscarriage they’ve been incredible, made the process much more dignified and comfortable. I sized up so they weren’t too tight as found previous versions have shrunk in the wash and glad I did, would recommend to do the same.

Very good

No, I don't recommend this

I have the plain material versions too and was a bit worried about ordering the lace ones as I had read somebody else's review saying they freyed etc My experience is different, they look really nice, I feel nice wearing them, they are comfortable, stretchy and Habe not freyed at all even after a few washes. I'll definitely buy more.

Great fit

Yes, I recommend this

Great i prefer the full pants but these are fab- always get a size smaller than your normal size as you want period pants to fit really snug

Pretty

Yes, I recommend this

Bought for those "oops" moments that ladies of a certain again get. The sizing is perfect, absorbency is good. Not sure how they will cope with regular washing due to pretty lace

Lovely soft lace

Yes, I recommend this

The are great period knickers and look much nicer that the usual ugly period knickers. Soft fabric with a nice stretch to them. Good at absorbing but like all period pants they do feel thick around the back side area.

Not for everyday at all

No, I don't recommend this

These looked stylish so thought I’d give them a go. 10/12 so picked a 12 for comfort. Was the right call but unfortunately the material just falls down and doesn’t hold where it should. They do feel nappy-like unfortunately and do not neutralise odour well at all. OK for night-time knickers when menstruating but wouldn’t want to wear during the day.

Great

Yes, I recommend this

Love these. I wish the padding took over more! It should cover more of the front and back. Because it’s lace it rips easily but out of all the panties this is my fave

Good idea and quality

Bought them as safety guards when out and about. Not too thick so is comfortable but I wouldn’t use them on its own.

Failed on first use

No, I don't recommend this

The absorbing fabric was placed too far back for me and so they leaked.
