Magic

Yes, I recommend this

The briefs are magic. So pleased I found them. So comfortable and super soft fabric. The main issue for me is when briefs don’t stay where they should. These are perfect

Simple comfortable knickers

Yes, I recommend this

Nice fabric, bought to match Rosie Silk & Lace bra. One size - not sure it would fit larger than a size 12. Comfortable to wear.

very flexible, good quality

Yes, I recommend this

Very flexible material, non see through. Good quality material and very comfortable. I`ve bought it for a dance performance, it gives good coverage. I love the seamless design, makes it invisible under any clothing.

Amazing

Yes, I recommend this

It’s amazing that these briefs fit lots of sizes and are comfortable. I first bought them in green to match a bra, liked them, so now I’ve got them in almond colour.

Perfect pants

Yes, I recommend this

Maybe I have reached 'that age' but these briefs are SO comfortable! The first time I bought them I was very doubtful of their 'one size' claim at the time I was a size 16. Sure enough despite looking tiny, they skimmed over me like a silky glove. I am now a size 10 and they fit just as beautifully. I have them in red, navy, black, white and natural.... says it all.

One size?

No, I don't recommend this

The one size concept will only work if all components expand proportionally. I'm not big (size 14) but the leg holes were too tight causing unflattering bulges. They went straight in the bin.

Disappointing - legs and waist cut in

No, I don't recommend this

Lovely fabric and style BUT they are one size (from 10-18) - plenty of room in the body but leg and waist elastic cut in (I am a size 14 so in now way did I expect this to happen) so no good for even slightly fitted clothing. Bought 3 pairs but returned the 2 pairs I had not worn.

Smoothing pants.

Yes, I recommend this

These are fantastic. Not at all like control pants but give a much nicer silhouette under clothing, especially a dress. And they are comfortable unlike control pants. Have 2 pairs and will be ordering more.

Not worth the money, not fit for purpose

No, I don't recommend this

These cut into your leg and do not give a nice silhouette of your bottom, but causes bumps due to the tightness of the leg.
