Great jeans

Yes, I recommend this

I already had these jeans in blue; very pleased with them so I bought them in black. They are a really “true “ black so I hope they wash well and don’t fade too quickly.

Rare find!

Yes, I recommend this

Very difficult to find straight leg trousers now and M&S are the worst ! Carrot top, barrel, jeggings, leggings, slim fit, wide leg - anything but straight leg 😡. These when you can find them instore and in sizes above 8, 10’s & 12’s are great but are a rare find as are the colour choices. More straight leg options please.

High quality jeans

Yes, I recommend this

Great quality jeans. The fabric is soft and not too thick. This makes them supple and comfortable. The colour is deep, true black. The jeans fit true to the size 8 Uk

Mainly buy bootleg but for a trip to Nashville thought these more appropriate. Lovely soft denim, perfect leg length and extremely comfortable. Perfect sizing and a great price.

Sizing not quite right for my shape

No, I don't recommend this

Rather baggy, but comfortable. I’m in between two sizes. Size 14 too tight and Size 16 too baggy. I really wanted them to fit as they are lovely jeans.
