Inconsistence sizing

Yes, I recommend this

Size 16 light flow bought approximately a year ago. Size 16 heavy flow bought more recently and is roughly a size larger than the previous ones. Otherwise, happy with actual garment and saves on wearing panty liners all the time. Down side is if you need to change whilst out and about a liner it is easier to change and dispose of.

Disappointing

No, I don't recommend this

I was really disappointed with these unfortunately. I’m a size 10-12 and ordered a size 12. They cut in to the tops of my legs and around my waist. Also despite being labelled as heavy absorbency they leaked after only 90 minutes and it wasn’t a particularly heavy flow day.

Underwhelming, but not without merit.

The pants fit well and do stop leaks. But pantyliners don't attach well to the lining, and the rather fuzzy material picks up fluff in the washing machine. I was looking for some underpants similar to those I bought several years ago from M&S, and these are a poor substitute. They are also very warm which is good in the winter, but would be unbearable in the summer.

Very high waist

Yes, I recommend this

The description didn't make it clear that these were high waist and they didn't fit me well at all. Luckily I was able to alter them. Apart from that they are good

Comfortable and look good

Yes, I recommend this

They are comfortable and fit well. 4/5 as I feel they are slightly less absorbent than previous heavy absorbency underwear I bought from M&S but I’d say they look better
