As someone who will give birth right in the middle of the summer I really needed a good pair of shorts. I love under the bump clothes, especially when it’s so hot. I’m happy to share with you this shorts pattern that goes up to sizes UK 18 US 14 EU 46. I’ve bought this cute jersey fabric from Moonbow fabrics.

Download and pattern assembly:

Scroll to the bottom of the post to download the pattern, it’s available in A0 and A4 format (works also with letter format). You can turn off the layers in Adobe Acrobat and print just the one you want. It will be easier to see the correct lines. You can find the option at View -> Show/Hide -> Navigation Panes -> Layers

Start with printing the first page and make sure the test box is 5 x 5 cm.
You can try printing on different paper formats but always select printing to 100%. Let me know if you have any issues.

Tape the pages as shown in the picture below. You can cut out the rectangles (remove margins) from the pages or just overlap printed pages

Seam allowances:

Seam allowances are included. You can see them on the pattern. Grey lines on the pattern indicate folding of the fabric after cutting and suggested buttonhole placements.

Recommended fabrics:

Jersey or other knit fabric with similar stretch.


3cm elastic and tape/ribbon for the waistband

Fabric requirements:

Under 1m of the main fabric. Width of fabric: 1.4m
See the suggested pattern pieces placed below.


Front x2 (mirrored pair)
Back x2 (mirrored pair)
Front waistband x1 (on fabric fold)
Back waistband x1 (on fabric fold)

Instructions (this is my preferred method, you can do it differently):

Cut all the pieces from jersey or other knit fabric with similar stretch. I’ve cut both shorts pieces & waistband from the jersey.

Sew leg sides together as in the picture on the side. You can use an overlocker or zigzag stitch (or any other stretch stitch). Press open.

Place one leg inside the other with right sides facing and stitch centre front and back crotch seam in one all in one.

Make buttonholes in the waistband. The grey line on the patterns indicates buttonhole placement & fold line as shown in the picture on the left.

Sew front & back waistband pieces together with right sides facing.

Measure your elastic & add seam allowances. It has to sit comfortably under your bump at the front. Don’t make it longer than the actual waistband

Sew folded waistline to the shorts leaving approx. 5cm gap for feeding the elastic. You’ll be sewing through two layers of waistband fabric and 1 layer of main shorts fabric. Make sure that you’ll end up with buttonholes at the front!

Feed your elastic through, overlap its ends by your added seam allowance and sew together.

Close the waistband seam.

Topstitch your waistband with two seams: one above and one below your buttonholes. You can use a straight stitch while stretching your waistband so that the elastic inside matches the casing outside in length.

Pull your cord/tape through the waistband.

Hem your shorts.
