I actually ordered a black pair as well but they are so much smaller than the other ones so I can’t wear them, but I love the other two, not sure what we can do about that, cheers Maree Glynn

When do I need to change them?
When do I need to change them?
It depends on your flow or level of leaks. Most ShineSisters can be worn for up to 8–10 hours, just like a regular pair of undies. On heavier days or if you’re unsure, it’s a good idea to bring a spare pair—just like you would with pads or tampons. You’ll know it’s time to change when the gusset starts to feel damp.
Do they feel like wearing a pad?

With the right care, your No Worry Knickers can last 2–3+ years or 100+ washes—making them a sustainable and cost-effective alternative to disposable products.

Very pleased
Love These!! Absolutely obsessed with these underwear, they look exactly like the photos, are comfortable, stretchy, moisture wicking and absorbent. They are by far the most comfy period undies I have ever owned! I now have quite a few pairs. Also, the returns policy and process with shinesister is so easy, I made a mistake when I ordered and got the wrong size and it was incredibly simple to change. Highly recommend these!
Finally the comfort I was looking for! I have birthed seven children. Therefore, I wear period panties every single day because a rogue sneeze can really be a bummer for me. I have had a hard time finding ones that are comfortable. They are often too stifling, or have a very thick, uncomfortable elastic at the top, or ride too low on the waist, or give a stark panty line, etc. The point is, I have not found a good combination of features in the many sets I have ordered. However, I am very happy with these ones! They are soft and light and breathable. They fit comfortably and land right where they should on the waist. They are not overly tight and causing bulges to form under your clothing. They are breathable and yet still offer all the protection you want for any leakage. I am really pleased with these, and will be ordering more.
These are amazing! No more stains on the sheets at night. No worries of leaks at work. These work so well and I wish I had These when I was younger. They are amazingly comfortable and they fit perfect. I don't wear them if I don't need them as they are a little bit bulkier than normal panties, but not bad. I wash in the machine and let air dry. I am very happy with this purchase.
I’ve been missing out! I just saw these and thought I will try them out. They are a game changer for me. I have no problem worrying about leaking when I sleep. They are breathable too. I never knew about period panties. I have always had cute underwear and of course the big ones for your cycle but, these make it that the pad doesn't slide and you are covered. I'm glad I bought these.
They didnt fit right ,felt un comfy
Brought 2 pair love these undies do everything they say will be buying more

Very comfortable love the colour does the job for small leaks great all round not hot to wear will be buying more
Very uncomfortable to wear and felt like plastic lining.
Too small
Sizing runs small. Not enough tummy room even though I sized up. Need to go up 2 sizes larger than usual.
Sizing runs small even though I sized up.
Sizing is very small. I sized up but still not big enough around tummy area.
Still the waist rolls down a bit, could be a bit firmer
love the fit very comfortable at 65 love the look and feel
Comfort, great fit true to size. Lightweight
I find them comfortable, soft on the skin, and my skin can breathe,
When my order arrived. I found they were not true to size. They are a little uncomfortable to wear. THey Don't come all the way to the waist and I found the elastic around the legs are to tight. Material is great but overall I wasn't overly happy.
These just aren't for me. The fabric is lovely and soft, but they feel like I'm wearing a nappy.
They fit well, and I love the colour, but they have not been used for the purpose for which they were intended so I cannot in all honesty give you an opinion. And believe me, at the age of 78 years I am not going to pose for a photo in them, lol. Cheers
Good fit
Don’t like the way they feel or fit
They are not full brief. They come under the belly button and not good for older overweight women. They roll down. I really would like to donate somewhere but cannot find anyone who takes under wear not in original packaging. Can you help please I happy to send anywhere in Australia
Great
I should have gone up to the next size
Your sizing is totally unrealistic.
Realistic sizing!
Best pants ever
Despite having bought the same size as my first order nearly two years earlier, I have found these a little too small. I am able to wear them, but they sometimes roll down under my apron tummy. However, I am happy to have them and have realized since starting to wear them, just how much the old ones needed to be replaced. They were no longer absorbing the wetness and odour as well as when new.
I find the underwear so comfortable to wear. When you see them they look heavy but when you put them on, they are very comfortable and you do not know that you are wearing them. The cut around the legs is very roomy and fit perfectly. Washing is very easy. Thank you for making them.
I have had a problem for years with incontinence a was really surprised that they work so well. I would recommend them to everyone
These are my second order. They are so comfortable
I purchased 6 pairs same size and 2 fit 3 are too tight and cut into me. So very disappointed regarding the pants
I bought 5 pairs and found out the sizing is not true to size if you are an 18 you need at least a size or two bigger as they do not have much give in them. But other wise they are brilliant well worth it. And peace of mind
Very comfy, great color and feel.

Lovely comfortable fabric very good size
I probably should have ordered a bigger size, as tight around thigh and the fabric irritates my skin , but that said these are are probably very good for other people
Waist is great but legs too tight. Same size as other style I bought but not comfortable.
