while absorbencies vary, they're perfect for periods, light bladder leaks, discharge, postpartum recovery, and even sweat. Whether you're sleeping, exercising, or on the go—they’ve got you covered.

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.

Nope! Our knickers are designed to be a complete replacement for disposables during light to moderate leaks. If you have a very heavy flow, you may prefer to pair them with a cup or tampon.

Great knickers! comfortable for everyday wear with no leaking.
Perfect seamless design, good coverage while i'm at the gym, no leaks!
This is the second pair of underwear I have brought from Shinesister, very happy customer once again, thank you.
I am able to do my daily walks with confidence
The underwear are huge. Like a nappy. Tried unsuccessfully to have them returned. Emailed many times. In the end I just returned them to the PO Box. Never heard back from them. Waste of money.
I love the fit and material, the back is a bit much for me and not great if wearing trousers.
They felt stiff and didn't fit well.
Great fit and very comfortable
I think it's wrong size, should of got large so sorry don't have comment
I expected there to be no spell but you can spell the urine in the liner
Very thick and nappy like - exactly the opposite to your ad. Very expensive, very disappointing
Felt like big thick nappies
They feel nice and great to wear. They certainly stop leaks going through to clothing. They are amazing if good at that. The issue I have experienced is the do not keep me dry, after slight leak I feel wet. The outside is completely dry. This may be the product is not suited to my situation as I feel it’s a good product however, I did go through 3 pairs to keep dry and have to wash in between. I am hoping this feedback is useful for further enhancing the product.
I love the fabric and the quality! My only recommendation would be to also do another style where the black gusset doesn’t go so far up the back. For women who wear them to avoid wearing liners
They were good quality but run very small
Great
Think twice about this one. Costly and bulky the complete opposite of the description above. Disappointed is an understatement .
The fit is amazing and they are so comfy! Very happy!
The fit is awful. Gaping legs. Horrible fabric.
I’m loving my new ShineSister purchase, never thought underwear could be so comfortable.
Firstly the shipping was extremely slow. I was beginning to think my order was lost. When it finally arrived I was quite pleased with the look but comfort was not so great. I also felt as effective as the underwear is. The odour is an issue. Back to the pads for me sadly 😞
Love them, the amount the hold is super!
Beautiful fabric & I love the no seams. Although even though I ordered small, I found the legs way too big so they were uncomfortable on & creeped. I am a standard size 10 so thought the small size should have been perfect. Shame, but just can't but up with the pants creeping up.
These are so comfy. They work beautifully
I have sent an email separately. This order was great the next two not so much sizing was all wrong !!
I love the fact they are a nice cotton feel but I don't like the feeling I am wearing a nappy, its uncomfortable for me. The quality is really lovely and very well done but sadly they are not for me.
Very uncomfortable around the back, they feel very bulky like I am wearing a nappy(not that I know what that feels Like),material is nice and soft, also found that they can be gappy in the gusset unless I really pull them up high. Not suitable under all clothes
Great product, true to size, washes well.
Nice fabric, comfy to wear, but I probably should have sized up.
As an older lady over 60yrs and set in my ways, I was skeptical to try but thought if I can do my bit to help save the environment I'll give it a go. After trialing for a couple of weeks I was surprisingly impressed and have now bought a further 3 pairs. Catches the "cough" leaks and all! Thankyou.
Comfortable and add confidence to my day.
Comfortable plus
Comfort and certainty!
The fit was small but I suspect I ordered the wrong size. It's very well made. A bit more structured than I expected. I will be buying the next size up. Better than wearing liners!
Not quite the right shape for me but seem good quality
I was so lucky to order on next size of my average e.g.: XL to 2 XL and its perfect size and comfortable to wear daily so far... As will purchase more order in next few weeks' time. Also like the type of Cindy High Waist, that like it to wear into so comfortable feeling.
They’re so comfortable Don’t know how they wash yet
I find them comfortable, so there is no need for panty liners anymore..I like the colours I I'll have to buy a few more before I go on my holiday..
very comfortable to wear they are a life saver
