School blazer

No, I don't recommend this

A nice fit, I’m 5ft 4 and a size 12. Unfortunately returned the item as the material and look just reminded me of a typical school blazer!

Great, basic go to.

Yes, I recommend this

I've been looking for a blazer for a long time. This one is just what I wanted. The shoulders are neat not bulky, there is just one button and it's a good short length (being petite). It's going to be a very useful item.

The perfect work jacket - and available in petite.

Yes, I recommend this

This is the perfect work jacket. The fact it comes in petite sizing makes it even better. The regular size was too long in the arms, and "boxy" shaped on me, I did try it for comparison but sent back. The length of the petite in the arms and shape of the body fits me perfectly. I'm so happy! I've bought both colours black and navy and really smart for work.

Lovely jacket.

Lovely jacket. Sleeves are always too long for me so I ordered in petite. It is just perfect, will stick to petite in future.

Great wardrobe staple

A lovely addition to my office wardrobe, beautifully tailored. I love that it’s machine washable, making it both chic and practical. A great piece that combines elegance with everyday ease.

Comfortable with Style at affordable price

Yes, I recommend this

Simple and easy care material and slightly stretchable making this jacket very comfortable to wear. Looks expensive and stylish as it is slim fit. Not too boxy.

Good value

Yes, I recommend this

Have deducted one star because of packaging. Although in a plastic bag and on a hanger, it was stuffed into an undersized bag and required some considerable time with a clothes steamer to make it wearable. Having said that I am pleased with the petite fit and overall look and style. Great value for money. I usually shop online as my nearest store is a 40 mile round trip, please improve packaging.

Good Quality

Not bad for the price. Slightly long in the sleeves even though I bought a petite size. Needed it to wear with a dress for a funeral. Slightly annoying that it wasn't available on Click & Collect which meant I had to pay a postage fee.
