The complexity of altering a bra sloper

I created this draft of a stylized bra design from my completed draft. It a bit complex if you have never done pattern drafting before, but know that there is a light at the end of the tunnel. When manipulating a pattern you need to remember this important rule – what you take away from one piece in volume you need to make it up on another pattern piece.

This isn’t going to result in a perfect fit after each pattern alteration, so it is important to test the fit prior to moving on to good fabric. I wish you all luck in this journey. The more designs you experiment with, they more knowledgeable you will become.

Here is my challenge. Draw a bra design and submit it to me for a drafting tutorial. I am open to as many as possibly. Let me know what your starting bra is and we can work from there. Not all designs must be created from your initial draft, so if you are daring, maybe submit the new design and scan and send in your starting pattern as well. The more challenges I receive, the more education I can pass on. You can email them to me at jennifer at porcelynne. For me to post, I will need to know which pattern you are starting from (if its another design out there) with the link to the product so I can share it will everyone.

Here are your videos for today.

Splitting the Lower cup from the Bra Draft

I have done a few new videos and this is the latest. This takes the drafted bra sloper we created and splits the lower cup for fit. This will help you get a better idea of the fit. Splitting the lower cup is really just for practice as you may not want a cup with a straight seam across the cup with the split lower cup. This is a good first step to understanding the manipulations involved with changing a bra draft.

Altering your Bra Pattern for a Different Size Wire

I worked on this little video after I had a few questions regarding using a different wire size with my bra pattern. This one is specifically for changing the wire size, but not the wire type. I will work on a different video for changing the wire type.

To Error is Human

I never claim to be perfect, so please never quote me as so. I actually skipped a step when drafting the back of the band, but this video shows you how to compensate for missing the step.

Drafting has Commenced

To put a smile on everyone’s face, I have finally filmed my first set of drafting videos for creating your own bra sloper. I’ll keep this short, as I know everyone wants to begin drafting yesterday, so here it goes. Happy watching!

I goofed again

For those of you getting ready to follow my draft, I just realized I goofed on a chart in my new book! Agg! I did this last time too. I swear all this math will get the best of me yet. I posted a bra size chart in one of my videos and it was off by 2 sizes on everything! I triple checked that stupid wire chart about 10 times and changed it that many times as well before the update of the book. I know it was correct, so a little gremlin must be sabotaging me. I’m so sorry if someone bought the wrong wire based on my video. I will make it up to you I promise.

Final set of measurements for the custom draft

I had intentions of getting this video done on Monday, but my shop was a disaster and I had to work on cleaning my desk off. I finally completed clearing my desk off yesterday, so here is the promised video. Please disregard my difficulty in holding my wires for measurements. Please measure in front of a mirror and not in front of a camera.

These directions are what you will need for your custom drafted sloper. I’ll begin recording the drafting tomorrow, but they might not be available until next week.

Another reason I have been slow to post is that I’ve been working on grading a new pattern for my website and in the process, I recorded the steps with the software on how I did it. Those won’t be available until after I complete the drafting directions, so know I have some goodies coming soon.

I make a mistake in the video when I’m talking about the wire size I’m using. See if you can find it.

Preliminary steps for drafting your own bra

I made a couple “raw” videos on measuring. These are just the first steps. There will an additional measuring video once we begin our draft. I will be filming the draft in many steps and will so shorter 5-8 minute videos of each step so its easier to keep up. But for now, this first video is a basic how to measure for your “standard” bra size. I put standard into quotes, because no body actually really fits a standard size.

The standard size measure is to find your starting point. In this video I measured 37 under and 41 over and chose the 38 band to work with. One thing I didn’t mention is that if I were to try on a ready to wear bra, I might also try the 40 band, but step down to the I cup.

Bras are complicated and there is really no one right way to do it. So take a deep breath and forget the numbers and letters you are coming up with and just go with the flow.

This second video is to help you determine which wires to try out when ordering. The larger the cup, the more challenges you might have, so you might need a wider range of wires to test. If you are smaller, meaning you are less than a G cup, you can probably try the suggested wire and then go up and down a size to test too. Bra making in its initial steps is going to be expensive, but once you have the hang of it, you will be creating beautiful bras and at a fraction of the price you’d be buying them in the fancy stores.

UPDATE: Before watching the following video- print this following chart out. I published the wrong size chart in both the video and the first printing of the book. I just updated it, so any new book purchases after 11-1-2016 should have the correct chart.

Remember that most places you order wires from do have a return policy, so extra wires can always be returned, but as a small business I need to express – you will be responsible for shipping costs for returns whether the wires you order fit you or not. And I know this goes for all the other bra wire suppliers out there too. Wires do not come in a one size fits all package. There can be hundreds to choose from, including demi, short, long, etc. The draft we will be working on is a full coverage “block.”

This means that this draft can be manipulated into other shapes and sizes, so your initial draft might not be the best shape for you. We will get to that after our draft. See you soon for our draft.

Adjusting strap placement

In this sample we are moving the strap placement.

Step 1: Draw in your seam allowance at 1/4″

Step 2: Take your two patterns pieces and overlap the seam line and tape down.

Step 3: Use the french ruler and reshape the strap position

Step 4: Cut off change and tape down to the new position.

Step 5: Separate the two pattern pieces.
