About this style

These Body Define™ firm control knickers offer a high-rise design that provides smoothing and shaping with comfortable control.

Made from innovative fabrics, the knickers deliver flexible support that moves with the body throughout the day.

Please don’t worry if the packaging name looks a little different, it’s still the same colour, our packaging just takes a little longer to update. Opaline formerly known as Almond.

Perfect for a flat tummy!

Yes, I recommend this

Excellent for holding your tummy in! Non-slip band means they don’t move & they were overall very comfortable

Nifty knickers!

Yes, I recommend this

Great garment holding me in at all the right places. It does have a tendency to roll over at the top after a while but a visit to the loo can sort that out.

Great underwear - and comfortable

Yes, I recommend this

Really impressed with these. Bought for enhancing my silhouette under a lovely, figure hugging dress at a Black Tie event. My dress felt big. I was comfy all night & even trips to the ladies went smoothly. Couldn't have asked for anything more

Overall, disappointing

No, I don't recommend this

Bought these waist cincher knickers to go under a dress for my neice's wedding. They are good quality and nice nude colour but they are really uncomfortable and whilst very tight, don't give your waist any definition at all. I'm only a size 8 so not large, but felt I needed something to give me shape at the waist - I'm in my late 50's and it's disappeared! Unfortunately they didn't do this at all. Also, the band around the top needs to be deeper, it's narrow and cuts into you. I ended up with a really sore red mark around my body - just below the bra line, that took about 3 days to subside. I'm afraid I won't be wearing them again.

Lovely light weight control pants. Whilst light weight, they are amazing at controlling the bulge. Really great price.

Purchased to wear under fitted dress. I purchased several styles and found this pair worked the best. Worth paying a little extra for.

VPL THIN

No, I don't recommend this

They were not as good as some of the reviews made me believe, first time putting on and went to adjust at the soft material at the back for no VPL and it ripped as i adjusted, very thin poor quality.

the quality is excellent

I haven't used it yet, but I think this model also has a problem with the belt. There's no adhesive tape to the body, and I think it will roll up.

Effective

Yes, I recommend this

I bought this garment specifically for an occasion. I was going to a wedding and my long dress was quite clingy. A friend recommended the waist cinch knickers and I ordered them online to be delivered just before the wedding. The fit was fine and they were very comfortable, holding everything in to give me a smooth outline. However, when sitting down the top band did tend to roll down and dig in, hence only giving 4 stars.

Perfect fit. Worked a treat! It’s hard to accept a growing waistline so this works well.
