Introducing the Otto Vest!

Fabric, fitting, and styling tips to help you sew this lined vest.

Posted in: Patterns • May 1, 2024

Introducing Otto, a lined vest with a timeless straight cut and modern details. It features a V-neckline, a shaped hem, and three buttons on the center front. Princess seams ensure a comfortable silhouette, and topstitching along the neckline, center front, and hemline adds subtle detail.

Otto is the perfect layer for a touch of sophistication. Sew it up in wovens like linen, denim, suiting, or corduroy, and find a fun lining. Wear it over a crisp shirt for a sophisticated office look, or pair it with a casual blouse for weekend outings.

The member bonus version of the Otto vest has a straight hem and a tie in the back, for a different silhouette.

















Fabric and Fit

Fabric recommendations: For the main fabric, look for medium-weight wovens such as linen, linen blends, denim, twill, suitings, and corduroy.

Look for lightweight woven linings such as cotton lawn, acetate, rayon, or silk for the lining fabric.

Seamwork Style Ideas

You can wear Otto on its own or layer it over another garment. Which is more your style?

Pair Otto with the new Erin trousers for a smart look that’s on-trend (but also never really went out of style). For another layer, find a cardigan like Lisa.

Wear Otto over a form-fitting top like Jenny. If you need an extra layer, try a lightweight coat like Baz.

Otto looks great paired with your favorite pants, like Nolan. Grab the Parker chore coat if you need another layer.

Ambassador Projects

Some of the Seamwork Ambassadors sewed up the new patterns already!




Allison sewed the Otto vest and the new Erin trousers.





Kathy sewed Otto in linen and skipped the buttons.






Angela sewed Otto in a heavy cotton sateen.






Alanna sewed the Otto bonus in a crinkled cotton print from Blackbird.

“I added a hidden pocket on the side front lining and installed eyelets at the side and center back to create double ties to cinch in the waist!. This is so fun as a layering piece for the Canadian climate! It pairs well with a sweater underneath in the cooler temps or on its own in the summer!”






Amanda sewed Otto in denim.

“I love that Otto let me dip my toes into the western trend! It also came together surprisingly fast.”





Ariane sewed the bonus version of Otto in a jacquard.






Emma sewed the bonus version of Otto in a washed cotton.

“This is the perfect casual top for the summer! I expect to make many more in the coming months.”





Alia sewed the Otto vest in this fun eyelet.

Vanessa added buttons to the lining of the Otto vest to make it reversible!
