I don’t know about you but I can sit around in comfy loungewear all day, every day! In fact, I have been wearing loungewear so often that I decided to DIY 4 new and different designs so that I can always feel comfortable but still put together when I’m at home.

Tools and materials:

  • Ruler
  • Chalk
  • Scissors
  • Elastic
  • Sewing machine
  • Pins
  • Fabric
Loungewear set

Make the pants 

To start I folded the fabric double the width of the crotch line and then drew a line down the middle of my folded piece. 

Draw a perpendicular line

I measured my desired inner seam length and then drew a perpendicular line. 

Trace leggings

I then traced the front and back of a pair of leggings I already had, leaving the leg wide for the shape of my new loungewear pants. 

Cute loungewear sets

Cut the pants 

After tracing, I cut out the fabric. 

Make a wider fit

I repeated the same steps for my new, cream-colored pants but this time I left a 3-inch gap by the center line so that I could have a slightly looser fit. From this step, the construction of both pairs of pants is the exact same. 

Sew the back and front seams

I started by sewing the back and front seams of the pants together. 

Sew the inner seam

Next, I opened up the pants and pinned and sewed the inner seams. 

Serge elastic

In this next step, I took a 1-inch piece of elastic and serged it along the wrong side of the pant waist. 


Once I had serged the elastic, I turned the pants right side out and folded the elastic inwards to create a neat and clean waistband. I headed back to my sewing machine to topstitch it in place. 

Hem the bottoms

While I was sewing, I hemmed the bottoms of my pretty, pink loungewear pants. 

Fold the fabric

Make a T-shirt 

To make the T-shirt option for my loungewear, I folded my fabric over four times so that there would be a two-layer fold. I then placed a folded T-shirt I already had on the fabric with the front, facing out on the fold. 

Trace the back neckline

Next, I traced the back neckline, shoulder, and the general curve of the sleeve to make a drop shoulder.

Trace all the way around

Once I had traced all the way around the T-shirt, I cut out my fabric. 

Cut the front neckline

I separated the two pieces of fabric and cut the front neckline on one of my pieces. 

Cut a 2-inch strip

Using the spare fabric that I had, I cut a 2-inch wide strip as long as the neck circumference of my new top. 

Best loungewear

I folded the strip of fabric and pressed it to hold the shape. I then slowly worked it around the neck, stretching the fabric as I went. I left a little bit of seam allowance at the start. 

Fold back the strip

Once I had measured the front part of the neckline, I folded the strip back and made a small notch on the point of the fabric where it would lie on the second shoulder seam. I then did the same for the back, adding a notch for the center point. 

Sew along the circumference

With the strip pinned in place, I sewed the two ends together and then sewed along the circumference of the neckline. While I was at my machine, I sewed the shoulder and underarm seams of the shirt as well. 

Make a cuff

I had quite a bit of fabric leftover so I decided to make a cuff for the sleeves to give a nice finish. I cut two, 3.5-inch strips of fabric with the length of the armhole. I folded the strip in half and sewed the ends together to form a ring. I then folded the ring lengthwise and placed it over my T-shirt sleeve. I then pinned and sewed the cuffs in place.

Leave the bottom raw

Lastly, I left the bottom of the T-shirt raw and just sewed a stitch along the edge of the fabric. 

Cut a bit longer

Make a long sleeve V-neck 

For the long sleeve shirt, I started by repeating the tracing and cutting steps that I had done for the T-shirt this time cutting the shirt a bit longer. 

Measure 5 inches

For this design, I wanted a slit on each side so I measured 5 inches and made a small notch in the layers. 

Cut V-neck

Next, I drew and cut a V-neckline on the front piece for my new top. 

Mark the sleeve width

For the sleeves, I folded the fabric four times again and then measured the same width as the armhole from the double fold on one end, and my wrist width on the other end. For my wrist, I added about an inch so that it wouldn’t be too tight. 

Connect the measurements

I then drew a line connecting my two measurement markings and cut. I added a small notch at the fold to mark the center of the sleeve. 

Add cuffs

I decided to add cuffs to the ends of my sleeves, so I made sure to cut the fabric to match the wrist of my sleeve. 

Fold right sides together

Next, I folded the two sleeves and two cuffs, right sides together, and sewed.

Sew on the cuffs

I turned out and folded the cuffs and placed them on the sleeves, right sides together. I sewed on the cuffs to get a cute finish for my long sleeve shirt. Looking back, it might have been easier to sew the sleeve onto the bodice of the shirt first and then finish it off. 

Women’s loungewear set

I sewed the shoulder and side seams of the shirt together, leaving the slits I wanted on either side. I then placed my sleeve inside the shirt, right sides together, and matched up the armhole seam with the sleeve seam. I went back over to my sewing machine to sew on the new, long sleeves. 

Add a neckband

I decided to add a neckband. I stretched the neckband along the neckline and let it extend a ¼ inch past the V-point for seam allowance. 

Overlock the edges

Before sewing, I overlocked the neckband ends at 90-degree angles and then pinned them at the V-neck point. 

Sew from the center

When it was time to sew, I started sewing a ¼ inch from the end of the neckband, right in the center of the V-neck point. I sewed about 1.5 inches along each side of the V point and then back stitched. To complete the rest of the neckband, I used a zig-zag stitch but if you have a serger, that works just as well.  

Iron the hem and slits

To finish, I ironed up the hem and folded over the slits twice before sewing. First I sewed the hem and then I moved on to sew the fabric along each slit. 

Comfortable loungewear

Make a cropped mock neck 

For the cropped mock neck shirt, I once again traced a drop shoulder T-shirt, and this time I made wider sleeves to add to the top. 

Cut a 6-inch piece

For the mock neck detail of this design, I cut out a 6-inch piece of fabric, wide enough to stretch over my head. I then sewed the neck seam of the mock neck and shoulder seams of my top. 

Fold over the mock neck

I folded the mock neck over so that its right side was facing out. I then stretched it along the neckline, right sides together, making sure the seam was at the back. I pinned the mock neck in place and sewed. 

Attach the long sleeves

I attached my sleeves, this time using the flat method. I then sewed up the side seams of the shirt.

Hem the sleeves and bottom

All that was left to do was hem the sleeves and the bottom of the shirt. For the bottom of the shirt, I did a cover stitch across but left the bottom raw.

I really adore my new loungewear! Which set is your favorite? Let me know in the comments!
