Great shape and fit - worth the money!
03 December 2019
Beautiful fitting trousers. Very long, but with my platform shoes on they’re fine.
01 December 2019
Lovely material and perfect fit. What a bargain
29 November 2019
As pear shaped the high waist didn’t fit right but that’s more fit of my body type than the trousers themselves
29 November 2019
Lovely material and style but far too long.
13 November 2019
Extremely long, would spoil if shortened
09 November 2019
Beautiful trousers just what I have been looking for. Beautiful material and not too wide for someone short.
30 October 2019
Brilliant fit very stylish
30 October 2019
Perfect pair of smart black trousers for all occasions.
29 October 2019
Lovely product, though have only tried on
25 October 2019
Good material hang well but far too long.
16 October 2019
Luxurious quality fabric but the length was extremely long and unwearable because of this. I am 5’7” Such a shame as I would have bought them.
15 October 2019
Okay if you're six feet tall or wear six inch heels, bizarrely long in the leg for a person of average 5'7") height
15 October 2019
The trousers is perfect. The design excellent. It falls away from the body. Bought one for my daughter as well and she can't thank me enough. Will definitely buy again.
07 October 2019
Great cut and finish. Will be used to replace my existing work trousers.
03 October 2019
Just the right fit and style
03 October 2019
Absolutely lovely trousers. Great fit for me, nips in on the waist but lovely flow through hip & thigh
30 September 2019
Excellent , heavy weight ,quality item. Perfect length ( 5' 8").
27 September 2019
These are excellent, beautifully tailored trousers in a slightly lighter black which happens to match a gorgeous All Saints blazer I got a few weeks ago. So now I have a perfect suit! Very pleased.
23 September 2019
Not for me! Just didn’t suit me.
13 September 2019
True to size and flattering fit. Look expensive.
10 September 2019
The size didn't fit. All my other trousers are size 16 and fit. These didn't fasten. Unfortunately I couldn't return then as my husband threw away the packaging. Have to diet now ...
06 August 2019
great quality, perfect size.
18 May 2019
Material and style of trousers great but as usual small made it is only trousers from phase 8 that has this problem.
30 April 2019
Excellent busy so not all products left in my size
23 April 2019
Love the trousers though, they're a really nice fabric that hangs really well and quite a flattering look in the black. I got a size 12 and would say true to fit, maybe erring slightly smaller than I expected but still fit perfectly.
09 April 2019
It's a great product, the only thing I didn't quite like was the high waist, but other than that a very nice style.
08 February 2019
First pair stitching wasn’t perfect but soon got swiped for fresher pair
04 February 2019
I had to buy a larger size than normal because of the cut.
27 January 2019
Beautiful fit. Size 16. Lovely colour top- pink. Perfect for the event.
