Good quality trousers with side zip! Marvellous. Side zip is what I look for.
09 December 2018
Lovely trousers shame they arrived damaged
02 December 2018
Have bought these before and wanted a new pair.
25 November 2018
A stylish slim trouser made from a heavy weight material with stretch. Ideal for work or casual wear.
05 November 2018
Nice material , stretchy, very comfortable
22 October 2018
lovely fabric. perfect fit for me
18 October 2018
Really like these comfortable trousers ideal for work
08 October 2018
These trousers have such a smooth line. Mainly because they have an unobtrusive side fastening. The material is also a good weight allowing the leg part to keep in shape.I hope more like this are made. I was so pleased with them that I now have three pairs....Two navy and one black.
03 October 2018
The trouser fabric feels good and is a good fit.
19 September 2018
not for me, they are very thick and have an odd texture inside from the fabric, also way to long for me as petite
04 September 2018
Pleased with fitting and look nice
28 August 2018
good quality and perfect fit
01 August 2018
Heavy fabric but although my usual phase eight trouser size, these would not do up.
30 July 2018
Returned as the legs were to tight and I have quite thin legs.
26 July 2018
Phase Eight has fantastic quality across it's range and these trousers are no exception. Really comfy, true to size, quite thick material so can be worn in cooler weather (and keeps opacity when bending!). Side zip feature adds to comfort and central seam down the legs is a lovely little design feature that makes you feel like you're not just wearing any old high street trouser.
03 July 2018
Lovely trousers that fit perfectly which is very rare for me!
03 July 2018
I ordered a size 12. They were rather stiff and didn't fit me well.
01 July 2018
Good fit a bit thick great for Autumn /winter
27 June 2018
Fantastic quality and excellent fit.
15 June 2018
Lovely fit with a little bit of stretch in fabric.
09 May 2018

26 April 2018
I love these, thick fabric- side zip and covers the belly for anyone who can’t wear their trousers low . Very comfortable! And lovely detailing down the front. Will buy a second pair
26 April 2018
Nice Style and fitted well I liked the material
24 April 2018
I like the material of these trousers, they are a very useful shape and fit well. However the side fastening is annoying and the metal hook fastener at the top digs in. I'd love it if you brought back the trousers in this same material with the front fastening and the more substantial trouser hook.
19 April 2018
Stylish and high quality as always. Perfect fit.
09 April 2018
Lovely well fitting trousers with slightly heavier material than anticipated.
08 April 2018
I actually had size 10 and they fitted well. They are well made and good quality for a smart pair of trousers.
03 April 2018
Excellent quality and service
02 April 2018
Comfortable, flattering & a good fit.
31 March 2018
The quality of fabric is not good too thick and heavy. Not pleasant to wear
30 March 2018
Love these trousers as they have 4% elastane in which makes them super stretchy and really comfortable. The fabric is quite thick so gives some tummy control too. Leg length to ankle perfect for me - I am 5' 7". I bought a bigger size to be sure of the fit but they were too big so I had to return them. However, I did get the next size down instore.
26 March 2018
Were a size 12 not 18. Really good quality would order again
25 March 2018
Ordered a size 10 and they were a perfect fit. Good quality material and the stretch in them is great. Really comfortable and look very smart on. Great length. I will be buying more.
23 March 2018
The trousers are very good quality and fit well
20 March 2018
Size 14 Black trousers excellent product could wear smart or casual
15 March 2018
So comfortable, lots of Lycra so what ever your shape they fit.
15 February 2018
Nice fit and for once the legs are long enough. Flattering fit. love the slightly heavier material.
30 November 2017
So comfortable yet stylish
30 November 2017
Didn’t purchase I gave up
28 November 2017
excellent fit and accurately advertised on line
16 November 2017
Love these trousers, have 3 pairs now, only problem is the zip is not very strong & have had it replaced on 2 pairs of the trousers.
22 September 2017
Excellent fit - I'm a size 12 and 5ft 4in Nice material , should be warm in winter
12 September 2017
Very comfortable and smart style. Will be a most useful addition to my wardrobe.
14 May 2017
I wish Phase Eight would realise that many women are not pear-shaped. These trousers did not fit me because they have been made for women with large hips and thighs.
20 March 2017
although they were very nice unfortunately they didn't fit
26 February 2017
Good quality material and styling
26 February 2017
The trousers looked perfect, lovely fabric but unfortunately were a poor fit for me. They were fine in the legs but too long (I'm 5'6") and tight in the waist. It was also a struggle to close the zip over the waistband, so I have returned them.
22 February 2017
Excellent fit (I had previously tried them on in-store), good quality product.
07 February 2017
Would have been a very useful pair of trousers and I really wanted to be able to keep them, but unfortunately they were too baggy on the thighs.
20 January 2017
I know these trousers r good and this is why i wanted a second pair sadly they r yet to arrive
18 December 2016
Very nice trousers. Good fit. Side zip can be slightly tricky and the hook and eye fastening at the top not sewn in very well. True to size and good quality.
18 December 2016
Great fit and quite dressy for night's out !
20 November 2016
Smart and comfortable
16 November 2016
they were a tad too short however they have a hem so I can organise letting down
15 November 2016
Unfortunately trousers did not fit well or look good on me
10 November 2016
Fits well side zip a bit awkward to do up
