What you have to say about the

All Woman Seamless Knickers

I've been a fan of your company for the past few years. I initially put extra, extra large tights into my search engine... up popped your website & I was thrilled to find tights & hold up stockings to fit my very generous curves! I've tried other so called extra, extra large tights & stockings but they've never been right. Your products are such good quality & long lasting. You occasionally send me emails with new products... loved the new knickers... the fit is perfect & they are exceptionally comfortable. Keep up the good work!


New design Pants have just arrived. A lovely natural colour and good shaping. I appreciate the wider than usual crouch. Many thanks may your business go from strength to strength.


Must to say I was delighted to receive my 3 pack of large size knickers today and they actually FIT- like a glove! I have had a hard time finding suitable underwear which doesn't dig in or falls down! So I am ordering another pack today! A BIG thank you from me!


WOW!!!!!!, Never come across a pair of knickers that fit like these, at last someone understands the importance of good fitting knickers, do not know you have them on!!!! Well done for this fantastic product.

Best undies!
So comfortable I'm buying more! I don't want to wear any of my other knickers again! :) I live in Australia, delivery was real fast, everything went smoothly. Thank you Big Bloomers Co!!

Wish I'd found sooner ...........
These are the most comfortable knickers ever! So comfy I have just ordered more. Love them, wish I had found this site ages ago. Was actually put off by name but now definitely a Big Bloomers fan! Thank you.....

Fancy Pants
I recently purchased 3 pairs of these. Very impressed with following:
The rise is great, fits on my waist very well
Comfort factor, they feel like a second skin
Stability: if like me, you are fed up with retrieving your underwear from below your tum, you will love these!
Sex appeal: when I saw these online I wasn't convinced. However, they look great from behind and are look much more attractive than other "full briefs" I have tried. High leg cut is flattering and the width of the front knicker ensures that my tum doesn't escape sideways! A bit graphic perhaps but actually these factors make me feel a lot more confident in my smalls! Will be buying more but for now, washing by hand rather than waiting for the next dark wash.

Fabulous fit
These knickers fit beautifully and are extremely comfortable. The only tiny downside for me, is that there isn't a cotton gusset which I prefer. Otherwise just brilliant!

Expensive but oh so worth it!
These are brilliant knickers. I bought a few pairs about 2 years ago, and they look as good today as they did then-mine have been worn and washed frequently, and they haven't gone saggy, haven't faded, haven't frayed or got worn looking. The initial cost is quite high, but overall value is fantastic given that they are near indestructible! They are also very comfortable-I've gone from a dress size 28 to a dress size 22 in the last couple years but because the fabric is stretchy and supportive without being clingy, they still fit just fine. OK, they aren't the most glamorous, but neither are they big granny pants, they look neat and attractive when worn. I doubt anyone regrets buying these, they really are fantastically comfortable.

Super duper pants!!!
Omg. I am so in love with big bloomers and your knickers. Where have you been all my life?!. I literally feel like shouting to the world that I feel knickerless in my knickers. Totally 100% brilliant. Perfect size. They don't move at all. Excellent customer service. Swift response to messages and fast delivery. I will be back for more. Thanks you so so much. Happy comfy customer.

Best knickers ever worn
Amazing knickers, I am in love! Ample generous sizing that hugs the body like they are not even there. Despite looking like sort of opaque tights material, they are unrippable as cotton knickers (if not more so) and cool and fresh on the nethers. Stay in lace offering very light support without pressing on the tummy, and no sausage cutting into the thighs. I was paying more for sloggie maxi support briefs and these are far superior in every way. Finally no arse munching on them as they sit like magical invisible knickers in all the places they should be. Believe the hype. You won't regret it if you've ever suffered cut groin/ thighs from over enthusiastic knicker elastic. *raises hand*

Great Big Bloomers
These are fabulous knickers. The fit is great the quality is great, they are quite expensive but well worth the money. Am about to order my second lot. Can't praise them highly enough, thanks Big Bloomers

Ordering more
I had a 3 pack of black a few weeks ago, like them so much that I'm always waiting for a dark wash to be done, so today I'm ordering the beige colour. They're really comfortable and a good fit.
