The return of the side zip!

Yes, I recommend this

Nice quality, they hang beautifully. Having a discreat side zip eliminates the unecessary bulk found with front zips , hence a smoother profile. The price is also good.

Perfect for the workplace as well priced.

Yes, I recommend this

I bought these because they are a good price for a pair of trousers for work. The waist on all M&S items are always too big! So I had to alter. I went on to purchase a pair in brown, but it would seem there are not many size sixes in the M&S inventory, so had to buy a pair in Long - and take up. But overall a decent pair of trousers for work.

Lovely smart trousers

Yes, I recommend this

They are very smart and look lovely on. I prefer a side zip to pockets. Not washed yet so hope they don’t shrink as they are a perfect length.

Length have changed

Yes, I recommend this

Lovely trousers that fit so well. However, Marks has changed their lengths and the regular now is too short for me. I am now trying to decide which between a regular and long will be better: the regular is just too short to wear with heels (I'm 5ft 5).

Great trousers

Yes, I recommend this

I’ve been looking for a nice pair of brown flared trousers for some time. I ordered a size 12 in short length (I’m 5’3”) and they are a perfect length when wearing with a small heel. The fit is really good and as it’s a size zip with no waistband they sit very flat on the waist and tummy. The fabric was a little lighter in weight than I had hoped for but to be honest it holds its shape well, died t crease and has washed no problem. So a really good deal for the price!!

Great colour and style. Poor sizing.

Yes, I recommend this

I was so pleased to see brown coming back into fashion. It’s a colour I love. These trousers are a great style and I like the fabric too. I have been a Marksaholic all my life! As usual these days I ordered in two sizes. Sometimes I order sizes 14 & 16 because M&S sizes have been so unreliable for some time now. In this case sadly one pair was too small and the other too large!
