Nice quality trousers

These trousers looked a felt good quality unfortunately they are very small I ordered my regular M&S size plus a size up, just in case, but I still could not fasten the zip. I was really disappointed to have to return them.

Too long in torso

No, I don't recommend this

M&S has got their pattern shaping wrong. I’m tall and have had to return two pairs of trousers recently, including these, due to an abnormally long torso/crotch. The cut is far too long in the body unless you have a very long torso or are prepared to pull the pants up and wear tucked over your ribs. Getting annoyed with the inconsistency in pattern making of M&S suppliers

Good quality

No, I don't recommend this

The trousers were well made and the side zip was a bonus but the length although regular flapped well over my feet. On that basis I shall be returning them

Flattering style

Yes, I recommend this

I purchased these trousers as I don’t like the wide leg ones. The flare makes me feel a little bit more fashionable without the bottoms flapping round my ankles.

Perfect Trousers

Yes, I recommend this

Saw these trousers in store and ordered my size online. I have been looking for trousers with a side zip. Very smooth across the body. More side zips please and more flares rather than wide leg. I ordered regular length and at 5ft 1 inch they were about an inch too long. Shortened them and are perfect with a heel. Very pleased with my purchase

Cruise must!

I’m a size 14S and these are extremely flattering as no pockets just side zip. The material is good quality and feels very expensive.

Great Quality Trousers

Yes, I recommend this

I always try to buy a bootleg or flared trouser as it suits me. These trousers are a lovely quality, good price and perfect fit. I am a size 12 regular, they were slightly long but not a problem. I also love the fact that they have a side zip so give you a nice flat front.

Size 12 Lovely Trousers however

Yes, I recommend this

I purchased a size 12 however found the thigh area way too slim so went up a size. These are a really smart pair of trousers and suit a newly purchased blazer/jacket in the same material mix. Great price!

Flattering, comfortable

Yes, I recommend this

18L very good, flattering fit. Comfortable with stretch and so far has not gone out of shape over the knees. Just long enough to wear with low heel. Chosen over the straight version which were shorter and looser obviously, much less flattering. Having just bought trousers, Sparks is now offering 20% off. Does anyone else find this happens? If they hadn’t been worn, I would return them and re-purchase!

Good value and quality item

Yes, I recommend this

I was very pleased with the quality and fit of these trousers. Having a side zip also means no unsightly ridge showing on the tummy area which shows with the normal front zip.

Slim side zip flared trousers

Yes, I recommend this

These trousers are great. They fit high rise and feel very neat at the waist due to the side zip. Very flattering. I bought my usual size 16 and the fit is great. Bought the brown colour first, but when I went back to order them in black they were sold out. Kept looking and was lucky enough to find them once more in black. Price £26 is excellent value.

Lovely trousers. Good quality and reasonably priced. Nicest trousers M and S have produced for a long time. Lengths are not always consistent however.
