A really versatile piece

Yes, I recommend this

A really versatile jacket that can be dressed up or down. It feels good to wear - it's fitted but with some stretch. I would strongly recommend this jacket.

Wardrobe must have

Yes, I recommend this

Lovely jacket. Nice fit. Works for both casual and smart. Colour not as grey as it looks on image. Jacket isn’t lined however it’s a wardrobe must have!

Perfect season transition piece

No, I don't recommend this

Great blazer for the autumn and spring months. It’s smart but can also be dressed down, and has become my go-to piece at the moment. Since it’s knitted, it provides a good amount of warmth. A faux pas on my part for not reading the description properly—I was expecting a jersey material, but it’s actually knitted. That said, I’m very happy with the look, style, and fit.

Nice fit. Nice stretch for comfort

Yes, I recommend this

This jacket arrived so creased. I considered returning it but it eventually shaped up with a bit of steam.
