It did what it should! Gave me more confidence!
15 April 2021
It’s going to. E seriously figure hugging!
23 February 2021
Does exactly what it says on the tin. Definitely one to pull up rather than pull over your head, but gives you a smoother silhouette. A good thing to have in your wardrobe!
17 February 2021
The item did not fit too tight
10 February 2021
Great design and does what it says it will-- holds you in and makes your shape look fab!
11 January 2021
Had fun getting on over my head. Much easier pulling it up. Snug fit, but looks great under dresses. I am a size 12 and ordered a medium. Really pleased with item.
11 January 2021
Fun attempting it on over my head. Much easier pulling it on from floor. Makes your dresses look good. Size 12 and ordered a medium. Excellent product and what I expected of item.
02 January 2021
Vergood dress to wear under your dress to give you that perfect shape
01 January 2021
Little longer than expected
20 December 2020
Was suggested by staff would be a good purchase to smooth the lumps and bumps. The technique to get on and off initially was hilarious, wish it had been filmed. Perfect undergarment
10 December 2020
This irons out the extra "wrinkles", taking a few years off my figure, giving me the confidence to wear fitted dresses - once I have wriggled into It!
07 December 2020
Looks very neat but fitted extremely well and felt very comfortable
07 December 2020
Just perfect under garment to the dress I purchased. For reference customers who purchase this garment should step into it as opposed to putting it over your head. This garment is a must for any dress.
04 December 2020
Fantastic to wear under a shaped dress. Smoothed me out a treat! and very comfortable.
04 December 2020
Gives great support and a very good length compared to many I looked at. I took a large size though I’m a 12/14 - would have struggled to get medium size on. Overall very pleased.
03 December 2020
As described but I'm not sure how often I would use this as it is a very, very snug fit ...
03 December 2020
I ordered a large and expected it to be tight but it was extreme. I am a small size14 and this slip was uncomfortably tight.
29 November 2020
Too tight across the chest and thighs. Not cinching enough at the stomach. Might suit someone with a different shape well enough, but not for me.
28 November 2020
Well made pretty flattering dress and lovely length
26 November 2020
Very supportive, need help to put on.
23 November 2020
Good fit. Will do what it advertises
23 November 2020
This is a smooth fitting garment which will be good as a lining for a fitted dress. Just what is needed
06 July 2020
Nice material, perfect fit, true to the size. Very elegant.
18 June 2020
Lovely fabric and fits well
05 June 2020
Quite a tight fit- but presumably that’s the idea. Did a good job of smoothing your silhouette although would need to consider what underwear to use so it doesn’t show
17 March 2020
16 March 2020
Amazing result
06 February 2020
I am a large person but the dress fits and looks very well on me.
07 January 2020
Purchased a black slip before Christmas and it was fabulous, so thought I would treat myself to the nude colour. Would highly recommend, gives a lovely finish. To any dress.
21 December 2019
I have tried it on at home but not with a dress over it. So far, so good. :-)
28 November 2019
Needs must!! Easier to step into!
26 November 2019
I have no idea what size to order these garments in - I am only a size 10 and got a medium but I got it over my head and couldn't get it any further.
01 November 2019
Fits lovely under my dress, giving a good silhouette
11 September 2019
Great slip for under phase eight dresses for a streamlined appearance. Comfortable and not restricted as you can be with some undergarments
27 July 2019
Flattering style. Pretty material. True to size.
23 May 2019
did not suit the occasion I bought it for
26 April 2019
An excellent item but not for me
10 April 2019
Perfect colour and fantastic fit.
06 April 2019
Good value for money just what I wanted
17 February 2019
A great dress. I bought it for a wedding but it is very versatile
15 February 2019
Had my eye on this dress but wanted to try in shop love it
26 November 2018
Fits really well and feels good on
10 November 2018
Fits very well and cannot see your wearing it
29 October 2018
The most comfiest I’ve ever tried on - hint: step into into it, rather than going for over the head and the risk of getting stuck!
24 October 2018
Perfect for under a fitted dress.
21 September 2018
Very pleased with my purchase very comfortable and does what it is supposed to do.
29 May 2018
Arrived on time, great fit would recommend
16 May 2018
Good quality and appearance really pleased
15 May 2018
I have only tried it on so far, but I was impressed by how comfortable it seems and it evens out lumps and bumps. I will need to wear a bra underneath though - the cups aren’t very supportive.
10 April 2018
Good quality and perfect fitting
10 April 2018
Good quality and perfect fitting
19 March 2018
Gives a seamless look and tightens any wobbles when wearing fitted dresses. Bra cups are a good fit
19 March 2018
Bought one in each colour and pleased with result.
21 February 2018
Lovely fit and holds you in
08 June 2017
fantastic, I feel 20 again ;)
10 March 2017
As it is called, worthwhile purchasing because it gives a lovely silhouette to a dress
01 January 2017
Rhona offered me a slip to try on 2 dresses - this turned out to be no ordinary slip, but like wearing magic knickers from midriff to knees! It is fantastic and not uncomfortable - it makes me stand better and it certainly flatters my shape.

I'll say good because I haven't actually worn it other than trying it on. But I like the fit and quality.

Very easy to get on and just the right amount of control without feeling you are uncomfortable, dresses look so much better with a smoother silhouette.
