Elevate your style with this navy blue blazer from Threadneedle Street Tailored for Boyd's. Perfect for any occasion, whether it's travel, wedding, party, casual or formal events, this blazer is a must-have in your wardrobe. It has a single-vented back, with a single-breasted cut and notch lapel style.
It has a two-button front and three-button sleeve button style make for a classic look. In addition, it has one chest pocket, two low pockets, where one has an interior smaller pocket.  Then, inside there are two additional pockets.  For a total of 6 pockets.
Unsure of the material or fabric.  The lining has a silk or satin feel, but not certain.
I measured the sleeves a total length of 25" and the chest at about 48".  The overall length measured at 34".
It does have tags within the pockets, however, no where does it show material make, size or further details. 
Dry clean only.

Please note, I am not a seamstress, I did the best I could to get accurate measurements.
