How to Add a Flared Sleeve Detail to Your Blazer - Free Sewing Pattern

Posted on November 2, 2020 by Lee Norris

A blazer is a wardrobe staple, whether you're working from home or not. For those of us confined to the small rectangle of our computer screen though, it may be getting tricky to add some style to your home office look. The Nepeta Blazer is an easy and somewhat casual blazer that lends itself well to a belted waist or leisure chic style. For this one, I skipped button closures and added large patch pockets, plus a cute sleeve detail. Let's take a look at how you can add a flared sleeve to your next blazer!

First, decide how long you'd like your sleeve flare. Double that number and at one inch. Since I wanted a 4" flare, I started with a rectangle that was 9" tall.

To get the width of your flare piece, measure the bottom edge of your sleeve and double it. Note: if you'd like to shorten your sleeve and then add your flare, make sure you measure the bottom edge after shortening it.

The bottom width of my sleeve was 10", so the width of my flare was 20". My final drafted piece was 20" wide and 9" tall.

Fold your flare in half and sew along the short edge with fabric faces together. Press the seams open and fold the fold the fabric in half the opposite way (like below) and press again.

Evenly pleat each flare into the bottom of your sleeves, fabric faces together. Your blazer can now be constructed following the original instructions. When inserting your lining into the blazer, it can be tacked to the new flare of your sleeve, hiding the raw seam allowance.

Create some ties or grab some drawcord to tie at the wrist of each sleeve. You can tack them to the inside seam of the sleeve so they don't get lost or add a belt loop or two - your choice!
