How to make a flared waist tank top (pattern drafting basics)

I wanted to show you a very easy pattern drafting for a top that flares from the bust down. To draft this, I first traced around a tank top I already owned and fit me well. The best top to trace from is a top in a similar fabric than the one you are going to sew you new top. If you’re using a woven fabric for your new top, use a woven fabric old top. If you’re using a stretchy knit, the more similar the stretchiness in your RTW (ready to wear) to your new fabric, the closest the fit will be for your new garment.

So, as I said, I just traced the tank top (you can use a t-shirt as well) for parts 1 and 2 in the pattern below and then for the pattern piece number 3, I added a curved wedge to the side.

You can move where the flare starts by marking your bust point on the pattern or have the flare start from the waist for a peplum effect. You can make it just a little bit flared, or design a very dramatic flare.

If you extend the top you can create a very simple trapeze shaped dress.

That’s it for today. Happy sewing and pattern drafting 🙂

Later edit: I see that Caroline Amanda also published a hack of the Sewaholic Renfrew top, but in her wonderfully explained tutorial, the volume starts at the shoulders, and not under the bust like my top. Fun stuff!
