DIY Maternity Tank Top (from any tank top pattern)

How to draft a maternity tank top form any tank top pattern

Hey lovelies! Didn’t think you’d see me again so soon, did you? Haha! In all seriousness, though, this is a post I planned on posting in December (!), but alas, here we are, at the end of April, and I’m slowly getting back into the game of posting here.

I made a grand total of 2 maternity sewing projects for myself. I know, it’s shocking even for me. When I once imagined being pregnant, I had these visions of having a handmade pregnancy wardrobe and what not. But, when the time came, I had a hard time investing time and fabric into something I would only get to wear for a couple of months. So, I resorted to mostly clothes I already had, could borrow from friends or thrifted.

Pretty early on in the pregnancy I realised how important it was to have a set of comfy tank tops. They’re perfect for loungewear and layering, so I knew I had to make a couple maternity-friendly tanks.

The process of turning a regular stretchy tank top pattern into a maternity one that I share in this post is something you can replicate with any tank top pattern you might have. And if you don’t have any, here are a few options: Zoe has a free camisole pattern, or you could try this or this pattern. I used one from an old Burda magazine that I’ve used countless times before.

You can also adjust this process to any other knit top pattern whether it’s a snug t-shirt or long-sleeved shirt.

Step 1

First, lay your front pattern piece on a new sheet of paper. I used this parchment paper that I got from a lovely reader (thank you, Geli!).

Step 2

Basically, what we’re going to do is add 5cm to the height of the pattern piece.

To do that, make 2 marks on the original pattern piece every 10cm from the armpit down. Then, trace the upper part of the pattern piece onto the parchment paper up to the first 10cm mark.

After that, remove the original pattern piece and measure about 15cm down from the 10cm mark (I measure 18cm down, but that was a bit too much) on the parchment (new) pattern and make a mark there.

Then, place the original pattern piece onto the parchment again, so that the 2nd mark on the original pattern piece aligns with the 15cm mark on the parchment. Makes sense? And trace the lower part of the original pattern piece.

I used my french curve ruler to curve the hem of the new pattern piece slightly more than the original hem. All for better belly coverage.

Finally, connect the 2 marks on the new pattern piece. Now you have a new front pattern piece.

All you need to do in the sewing process, is to gather the middle part of the new pattern piece that is now 15cm wide into 10cm (like it was) before you sew together the side seams.

I hope this makes sense to you. I really need to write these tutorials right after making the item, so I can better remember the whole process.

The one thing I’d do differently would be to go a size up with the pattern. I used a size 34 as my base, but I should have gone with 36. Fortunately, both fabrics I used (I made one in black as well) had a good amount of stretch in it, so they both still fit me now that I’m 36 weeks along.

This is definitely one of the maternity sewing projects that is worth investing your time in. I’ve worn these almost every day for the past 4 months, and I’ve missed them a lot when they were both in the wash.

What did you sew during pregnancy and do you think it was worth it in hindsight?
