because they all share the same wire size. Reading across this chart, you can see that the 36K has sister sizes of 38J, 40I, 42H, etc. The 36K in our example would be the highlighted space in the wire chart: Use the wire chart to find where your size would be. Step 3: Find where your size would be on the wire chart

In our example, a 12″ difference between the band and full bust would be a K cup. For differences greater than 11″, continue going up the alphabet.A difference of 1″ would be an A cup size and a difference of 2″ would be a B cup.What do you do if the difference is less than 2″ or greater than 11″? To find your cup size, subtract your full bust measurement from your band size and use this chart:ĭifference between full bust and band size If your underbust is an odd number, subtract 1 from your underbust.If your underbust is an even number, that is your band size.What do you do if your underbust measurement falls outside of the chart above? In our example, the underbust measurement of 36″ would be a 36 band. Use your underbust measurement to find your band size in this chart: Band size Sister sizes are different bra sizes that share the same wire size. You can use what’s called “sister sizing” and the wire chart (not the size chart!) to modify an existing pattern to fit. If you fall outside the range of sizes included in the Willowdale, it may still be possible to use this pattern to create a bra that fits.įor example, let’s say you have an underbust measurement of 36” and a full bust measurement 48”.Īccording to the size chart you do not fit into one of the pre-determined sizes. What if your measurements put you outside of the size range?

Once you’re able to try on your Willowdale, refer to our bra fitting guide to determine what (if any) adjustments you would like to make. If you want to be able to reuse your elastics and notions, you can baste them onto your muslin and remove them once you’ve assessed the fit. You need to make an entire bra to get the best sense of the fit, because the various tensions through the fabric and elastic make a big difference, especially for large cup bras like the Willowdale. By doing that, you’re ensuring that your fitting process will result in a bra that fits at the end. For that reason, the IDEAL approach is to use the exact same fabrics for your muslin as you intend to use for your final bra. The fabric that you use for a bra can have a radical impact on fit-as in, you could achieve a perfect fit with one fabric, and then you a different one and it barely fits at all this is much more so than when you’re fitting say a top or a dress. Here is where bra fitting is a little more tricky than regular garment fitting. So once you’ve determined your ideal starting size, the best thing to do is to make a muslin (test version) to check the fit. We’ve worked hard to design a bra that will fit you well out of the gate, but boobs can vary so much in shape and size, and it’s impossible to capture the true shape of your bust with two measurements. The Willowdale has been designed for use with a rounded, regular underwire such as the regular heavy duty underwire from Porcelynne. Use your Willowdale size that you identified in Step 2 to figure out what wire size you’ll need. If you don’t see a size at the intersection of your measurements, you may still be able to create your ideal size in the Willowdale! Skip ahead to the section titled “What if your measurements put you outside of the size range?”. Important note: this chart cannot be used to determine sister sizes (more on that below). Use your two measurements and the bra size chart below to identify your bra size. Hold the measuring tape taut but be sure to breathe out. Your underbust is measured directly below your breasts, at the narrowest part of your rib cage, where your bra band will sit.

This is the part that would hit the wall first if you walked directly into a wall, and may or may not be your nipples.Ģ. Your full bust is measured at the bust apex, which is the fullest part of your bust. There are two key measurements you’ll need to take to select your size: full bust and underbust. It’s important to take these measurements at the start of every project, and try to wear your most supportive bra while doing so, if you have one (if not, just go with your best option!).ġ. So let’s start by taking our measurements. Since bra sizing varies considerably, we recommend choosing your Willowdale size based on your measurements. So we’ve put together this guide to help you find your starting size. Bra sizing varies SO MUCH from country to country and from brand to brand, and your ‘regular’ bra size may not be your Willowdale size. The first step to making a bra that fits is to calculate your ideal starting size.
