A perfect fit, great material {haven't tested whether it is waterproof}. I particularly like the length and colour.

Really pleased with the coat. It's exactly as described and true to size. As others have mentioned, the sleeves are a little bit long but I like that.

Lovely coat, been looking for a raincoat with a hood for some time. Only 4 stars because I didn't realise I had to use the recommended re proofing after a few washes. Hope M&S can supply it!!

I don’t love it!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I bought this raincoat to replace one I have had for years. I had tried a size 16 on in store, but found the slightly too tight across the bust, so ordered a size 18 on line. I probably wouldn’t recommend this item and would suggest trying on in store before buying. The fit across the bust is not generous and I’ll only be able to wear a thin top underneath. The sleeves are extremely long. I would return, but have not found anything more suitable.

Summer raincoat

Originally posted on marksandspencer.com (UK)

Bought to protect from summer downpours in Cumbria. Not used yet so can't vouch for the waterproofing but am hopeful having read other reviews. Fit is great and coat is smart enough to wear around town. Bought in cream/beige colour. The contrast, navy zip detailing is good.

Good quality and actually waterproof, but

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

The coat is well designed and made, with two zipped side pockets, one zipped breast pocket and an internal pocket, with Velcro fastening, big enough to hold a mobile phone. Yesterday was the first time I wore it in torrential rain and it is genuinely waterproof. I would have given it 5 stars but I feel it could be longer. I am 5’4” and it comes above the knee. When I got home my trousers were drenched from about 3” above the knee. Another thing to bear in mind is that if you need to wash it, it will need to be re-waterproofed. This is an expensive coat and the cost of the recommended waterproofing products may need to be factored in when deciding whether to buy.

The jacket is exactly as shown in the photo, maybe a smidgen darker in real life. It is true to size and very flattering at the waist. Beautiful quality that will last many autumn/winter seasons.
