The Cassis Tiered Sleeve Blouse Free Sewing Pattern

Meet the Cassis Tiered Sleeve Blouse, a luminous staple designed to bring effortless elegance to any wardrobe. Crafted in a gorgeous ivory viscose fluid satin, this blouse drapes like it was poured onto the body, catching the light with every movement for a soft, radiant glow.

The statement sleeve features three tiered layers, creating beautiful volume and fluid motion, while a delicate bow at the collar adds a playful, feminine touch. At the back, a row of cloudy buttons secures the neckline, finishing in a subtly flirty keyhole detail.

Versatile and elevated, the Cassis Tiered Sleeve Blouse pairs seamlessly with jeans for a polished everyday look, a pencil skirt for the office, or layered over a tweed mini dress like the Lunette Cocktail Dress for a more styled ensemble. Best of all, this pattern can be sewn in a day and worn out the very same night.

Find Your Perfect Fit

The Cassis Tiered Sleeve Blouse Sizing Guide is based on the suggested design & wearing ease for this style. You can also choose the size according to your desired finished garment measurements, blending between sizes as needed. Measure the printed patterns to make sure the dimensions are according to the desired fitting and adjust if needed before cutting the fabric. For best results, sew a test garment in a similar fabric to adjust your pattern.

Note: Always read all the instructions before cutting the fabric!

How to Sew The Cassis Tiered Sleeve Blouse

The instructions provided below are designed to guide you through sewing the Cassis Tiered Sleeve Blouse from start to finish.

4 Tips for Sewing with Fluid Viscose Satin

⇒ Pre-shrink your fabric before cutting out the pattern.

⇒ Use a super skinny, super sharp microtex needle (like size 60/8 or 70/10) to prevent pulls and skipped stitches.

⇒ Press every seam open unless otherwise instructed.

⇒ Use a lot of pins while cutting and sewing to prevent the fabric grain from shifting and warping while you make this garment.

Sew with a 1/2″ seam allowance for all seams unless otherwise specified.

Step 1 

KEYHOLE

1. Cut the keyhole down the top center back of the blouse as shown in the paper pattern.
2. Cut out a strip of fusible interfacing that is 1 inch longer than your keyhole and 2 inches wide.
3. Cut the strip of interfacing down the middle, but leave 1 inch of fabric attached at the bottom.
4. Pin the keyhole facing right sides together with the keyhole on the back of the blouse (this means the right side of the viscose should be touching the NON-STICKY side of the interfacing. You’ll see why in a second).
5. Sew the interfacing to the perimeter of the keyhole with ¼ inch seam allowance.
6. Clip the bottom corners of the keyhole so that the interfacing can be flipped.
7. Flip the interfacing towards the wrong side of the fabric so that the raw edges are hidden between the interfacing and the back of the blouse.
8. Press the interfacing with an iron to fuse it to the wrong side of the back of the blouse. Make sure none of the interfacing shows from the outside of the blouse.

Step 2

PREPARE SLEEVES

1. Fold the smalled of the 3 sets of sleeves in half right sides together with the sleeve inseams lined up.
2. Pin and sew the sleeve inseams.
3. Press the sleeve inseams open and flat.
4. Hem the bottoms of the sleeves with a ¼ inch double rolled hem.
5. Press the sleeve hems.
6. Repeat for all 3 sets of sleeves.
7. Stack the sleeves inside each other so that the longest sleeve is the innermost, the medium sleeve is in the middle, and the shortest sleeve is the outermost.
8. Pin the sleeve caps of the three sleeves together.
9. Sew a stay stitch around the sleeve caps with ¼ inch seam allowance.

Step 3

ATTACH SLEEVES

1. Insert the sleeves right sides together into the armscyes of the blouse, making sure that the front and back of the sleeves are lined up with the front and back of the blouse.
2. Pin and sew the sleeve caps to the armscyes.

Step 4

PREPARE BOWTIE

1. Place the bowtie pieces right sides together (you should have two mirrored sets).
2. Pin and sew around the two long edges and the pointy diagonal edge of the bowties, leaving the short flat end open to flip them right sides out.
3. Clip the pointed corners of the ties.
4. Flip the ties right sides out and press them flat.

Step 5

PREPARE COLLAR

1. Layout the front collar piece.
2. Place the raw edges of the bowties on top of the raw edges of the sides of the front collar.
3. Place the back collar pieces right sides together on top of the bowties and front collar piece.
4. Pin the side seams of the collar with the bowties sandwiched between the layers.
5. Sew the side seams of the collar and press the seams open and flat.
6. Attach the other set of collar pieces the same way you attached the first set, but without the bowties sandwiched between the layers.
7. Place the collar piece without the bowties right sides together on top of the collar piece with the bowties.
8. Pin the top edge and sides of the collar pieces together.
9. Sew the three sides of the collar together.
10. Clip the corners of the collar then flip it right sides out.

Step 6

ATTACH COLLAR

1. Line up the neckline of the blouse with the raw edge of the outer layer of the collar (the one with the bowties).
2. Pin only the outer layer of the collar to the neckline of the blouse.
3. Sew the collar to the neckline.
4. Press a ½ inch fold into the raw edge of the inner collar piece.
5. Pin the folded edge of the inner collar directly on top of the collar seam that you just sewed. Make sure that the folded edge of the inner collar is sticking out just slightly below the collar seam. Also make sure that the entire raw edge of the neckline is sandwiched between the two layers of the collar.
6. From the outside of the blouse, topstitch a stitch in the ditch to attach the inner collar to the neckline invisibly.

Step 7

HEM BLOUSE

1. Create a ¼ inch double folded hem on the bottom of the blouse the same way you did in step 2 for the sleeves.
2. Press the hem.

Step 8

BUTTONLOOPS

1. Mark the desired location for your buttons and button loops on the center back collar of the blouse.
2. Thread a needle so that there are two strands going through the eye of the needle (4 threads hanging from the needle) and tie a knot at the end of the thread.
3. Thread the needle through one of the chalk markings you made.
4. Begin crocheting a chain stitch with the thread with your hands (or a crochet hook if you have one, but I just used my fingers). To start a chain stitch, start by tying a slip knot into the thread. Make sure the knot of the slip knot is flush against the right side of the fabric.
5. Reach through the loop of the slip knot and grab the loose thread. Make a new loop with the loose thread and pull the previous loop tight.
6. Repeat these steps over and over until your chain is long enough to fit around the perimeter of your button.
7. Poke the needle back through the back of the thread once the chain is long enough and tie off the hand stitching with a knot in the inside of the blouse.
8. Make another one of these button loops on the other chalk mark.

Step 9

BUTTONS

1. Hand sew buttons on the center back neckline at the chalk marks opposite to the button loops.
2. Button the buttons and tie the bow at the front of the blouse and you’re ready to wear it!
