Size information: The Katharine blazer is double-breasted but slim, however it is not designed to be fitted. If you are in between sizes or want a more oversized fit, we recommend sizing up. (We love the look of a blazer with a little extra room) Our size chart below provides garment measurements taken when the garment is laying flat and buttoned. We have found using these garment measurements and comparing to measurements of a similar jacket or blazer you may have in your closet (this does not have to be exact) has made sizing more accurate.

Care: Machine wash, inside out, in cold water at gentle cycle. Wash separately (preferably in protective mesh bag). Reshape and hang to dry. Iron at low setting.

Best in Class

I have tried 100s of blazers from leading designers and none come close to the quality and style of the Katherine blazer. The blazer is exceptionally well made… even my 80 year old British granny who makes all her own clothes said so. The ponte material provides stretch, but still somehow looks chicer than wool. It has stretch to wear over a sweater, but looks chic over a tank. I ordered one size up as the 10 was out of stock, but the oversized also looks so cute and still has structure without looking sloppy. The gold buttons are gorgeous and provide a formal touch. My all time favorite blazer. Thank you Classic Six team!!!

Perfect fit and material

The reviews are so right. I love this blazer. It’s so comfortable and the detailing is even better in person. I ordered a 10 (same size as my Gabrielle and Veronica Beard blazers), but it was too big. Exchange was easy and the 8 looks much more fitted.

Must Have Blazer

Such a quality classic styled navy blazer. Beautiful details - gold buttons and white piping in the lining. Great fabric, good feel with just enough stretch. Can be styled with so many pieces.
