Perfect jeans

Yes, I recommend this

These jeans fit perfectly and are incredibly comfortable with just enough give. True to size, perfect length and good colour. They wash well and look smart.

A bit stiff.

Will see if they soften after a wash. This range is usually softer.

Changed the fit!

I have a pair of these already which I love and fit so well! I bought a second pair in the same size and length only to find that the fit has changed with them sitting much lower between the legs, the waist is almost an inch smaller than my previous pair! I do like that the button is now black so they look smarter. They still fit but don’t sit as well as my last pair. Such a shame!

Fantastic fit

First pair of jeans since weight loss and the fit is excellent. Super comfy, smart and they look good. The sizing however is a 16, whereas I am a 12 or 14 in other clothes, so you may need to go up a size. Bought them in blue and black.

Disappointing

No, I don't recommend this

I've found short too long so tried extra short but they were not a good look on me, so I've returned them. Still hoping to find the right fit, in your reason for returns no mention is made of length.

Why spoil it with a pale wash on the upper thigh

No, I don't recommend this

Fitted well but button very difficult to use. Returned as the colour on the upper front thighs only was a very pale wash compared to the rest of the trousers and looked distinctly odd. Such a disappointment.

Not ideal, but good.

Yes, I recommend this

I like the high waist and the straight legs. I would not call them super soft, the fabric is winter weight and tough. They haven’t softened after washing. Not much ‘give’ so they seem tight.

My go to jeans

One of the few jeans I have found to comfortably fit size 24 and not make me look enormous. Come up nice and high and long enough to not flap around my ankles

You need to size up - Sienna High Waste

Originally posted on marksandspencer.ie

Lovely jeans but you deffo need to size up. Size 12 was more like a size 10. Had to order size 14. Also, they are longer than their normal short length.

Sizing all wrong

Originally posted on marksandspencer.ie

No, I don't recommend this

Been buying these jeans for the last 8 years or so. But sizes are definitely wrong. Bought Suze 16 short as per usual. They are more like size 12. I compared jeans I have with the the ones I received and they are definitely smaller. Won't be buying again.
