Review by Fran (Posted on 17/07/2016)
Very convenient that they are machine washable. They are made with a good quality fabric that will last quite awhile if taken care of. The price was very low compared to other slimming products on the market. Recommend to all others looking for a way to slim out their physique. *
Review by Catherine Logan (Posted on 06/07/2016)
This is a fantastic product. I bought these to support my wobbling tummy when I went back to running after having twins. I feel supported, strong and even shapely. No muffin top. They gave me the confidence I needed and made running possible again. They have lasted incredibly well over time, and wash well. Great quality.*

I feel like a new woman Thanks*
Review by Mary (Posted on 06/07/2016)
Did wonders for my party frock before my diet, don't need them anymore thankfully! but were great for the special occassion where i needed to 'lose a few pounds' can recommend, made my very sleek dress look sleeker. really make you feel more confident if you are a little weight concious. *
Review by Harriet S (Posted on 06/07/2016)
My sister recommended these to me so i said id give them a try.
They are very good.
I am a size 12 to 14 (5 ft 9) with large thighs and saddle bags and unfortunately a bum that is flattening at an alarming rate!
The tummy control is so-so but i have quite a flat tummy so that didn't bother me.
Where these worked best (for me) was in the bum lift. it was excellent and gave a lovely BUNS shape!
As well as that it smoothed out the thigh area for wearing dresses. I am so happy i am back to buy a black pair now. *
Review by Emily (Posted on 06/07/2016)
This is the best price I have found for these and I know I have made a good choice with them. They dont keep falling down like the M&S ones that I previously bought. They really hold flabby bits in and definitely improve your shape. I find then comfortable and a very good purchase.*
