About this style

These Body Define™ firm control knickers offer a high-rise design that provides smoothing and shaping with comfortable control. The waist-nipping effect helps define the silhouette while striped sheer panels add a touch of elegance. 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.

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.

Highly recommended

Yes, I recommend this

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

This is too long

No, I don't recommend this

For knickers it is much too long - knichers would usually finish at the waist - not upwards to the bust! The sizing is also quite small.

Good undergarment!

Yes, I recommend this

Does what it's designed to do. Sucks you in and keeps tummy flat. Very happy with it.

Suck it all in

No, I don't recommend this

Lovely idea but it’s not long enough in the body for me. Does the job though, but I needed to keep pulling it up.

Comfortable and high quality material. Great value. I wear these with my bodycon dresses these days as have gained some menopause weight. These made me feel more confident and less self conscious.

Comfortable

These are great. Comfortable and give a great shape. No roll down on wearing. I've had one pair come apart at the gusset, though.
