Breastfeeding Sewing – Indigo Hack

Hey everyone,


Hope you are all doing well, even with the UKs heat wave! I’m currently 29 weeks pregnant, so the heat wave is not at all welcome!!


I am finally bringing you the next breastfeeding hack. If you follow me on Instagram you will have seen me getting rather frustrated with this one. Not because the hack itself was hard, or that I didn’t like the concept… instead it was because I used some awful interfacing for the facings, and it made the whole top not sit nicely. But luckily Freya, of Crafty Sew and So, spotted my posts and came to the rescue with some excellent quality interfacing. So she definitely saved the day/project!


The last two weeks I have been hacking the Tilly and the Buttons Indigo top and dress. This pattern has been super popular ever since it was released, and there are so many incredibly versions on the #sewingindigo hashtag on Instagram. I have made 3 versions myself and really love wearing them. It’s a smock shape, which is ideal for the baby bump, but also for feeling comfortable with the gained weight after child birth. Hence why this was on my list of must haves for post-partum.



The hack itself is really simple… I decided to add a zip in the centre front for the access. Zips are amazing, and definitely a breastfeeding mamas best friend. I love how it worked out, but especially because I made the time to pattern match the front bodice, making the zip appear even more invisible. Perfection… easy access while not screaming breastfeeding clothing.



So things you will need for this hack:

  • The Indigo sewing pattern
  • Your fabric
  • Sewing supplies
  • Ruler, paper scissors and some extra paper
  • 10-12″ Invisible zip


My fabric is a stunning Dashwood viscose from the lovely Guthrie and Ghani in Birmingham. It is a very special fabric and it is a matched made in heaven with the Indigo pattern.



Right, let’s get to the hacking…


  1. Cut out all your paper pattern. We will be adding a seam at the centre front, so you need to also add a 5/8 inch seam allowance to the front bodice at the centre (rather than it being on the fold).



  1. Sellotape the front facing to an A4 piece of paper. Add a 5/8 inch seam allowance to the centre (to match the main bodice). We want the facing to run all the way down the zip, so we will need to extend the facing down, perpendicular to the existing facing (as shown in the photo below). I made my facing have a width of 3 inches.



  1. Cut out all the pattern pieces in your chosen fabric. You will have 2 front bodice pieces, and two front facings, as well as all the usual pattern pieces.
  2. Interface the front and back facings.
  3. Sew the front facings to the back facing, right sides together. Press the seams open.NmL6xxurQAiA7ixVMpAtOw
  4. Sew the darts in the front bodice as per Tilly’s instructions.
  5. Line up the bodice front and bodice back pieces at the shoulders, right sides together. Pin and sew, using a 5/8 inch seam allowance. Press the seams open
  6. We will now add the zip to the front bodice. Line up the zip teeth to the 5/8 inch seam allowance. Using an invisible zip foot for your machine, sew the zip in place.

There are many zip tutorials online if you need full and in depth instructions for this!

  1. Line up the facing with the bodice neckline, matching up the shoulder seams, centre front and centre back. Pin all the way around, and sew. Leave the facing down the bodice front unsewn for now.
  2. Clip the neckline seam allowance, and then understitch the neckline, as per Tilly’s instructions.
  3. With right sides together, pin the facing down the side of the zip, lining up the raw edges (the zip needs to be unzipped for this bit). You will then have the zip tape sandwiched between the bodice seam allowance, and the facing. Sew.



You can now go back to the official instructions, including sewing the facing to the bodice at the shoulder seams etc.


The zip being the length of the bodice front gives a great access to the breasts so I would highly recommend adding one that is the full length and not any shorter.


Hope you have enjoyed my latest hack as much as I’ve enjoyed wearing it.


As always, please do share if you use my hack. I would love to see what you create.

See you next time for another boob friendly make,


Love, Abigail x
