Are You Overfitting Your Wires? A look at breast root anatomy
Bra making has taken a very modular turn in the past few years: to make a well fitting bra, you must: Take a root trace (while leaning forwards) Match this to a wire chart and order some similar wires Make a fitting band to fit your wire and band Add the cups and fit those…

Should you worry about bending your wires? (A response to Bare Essentials)
For those who are unfamiliar,”Bare Essentials: Bras” is a book by Jennifer Lynne Fairbanks, which is most known for its unique bra drafting techniques which allow you to make a custom bra draft based on your measurements. I won’t be talking about those in this post – the book is expansive and also covers bra…

Bra Physics 4 – What can we learn about the cups and straps?
In this part, I talk about the physics involved in the cups and the straps. The cups are by far the most complex part of the bra, and their geometry befuddles millions of people worldwide. I won’t be talking about geometry here – cup shape, strap positioning, and necklines (well, I do a tiny bit…

Why the Omega Alteration keeps messing up your armpit (and how to fix it)
There are a few different adjustments you can make when altering a pattern to fit a smaller frame – Emerald Erin has a great rundown here. One that I have mentioned before on this blog is called the omega adjustment. Now, a bugbear of mine is that while this is called the omega adjustment, doing…

2 Ways to Widen the Lower Gore – Wire Spring vs Wire Rotation
Widening the lower gore (aka the lower bridge) is a common alteration for those with a splayed root shape, but the techniques in this post can also be used to turn a regular wire into a plunge wire. Here’s two ways to widen the lower gore, each with their own advantages and disadvantages. Wire Rotation…

Bra Physics Part 3: What can we learn about the wires and cradle?
This is Part 3 of my Bra Physics series. In Part 1, I described the forces involved in supporting your breasts and what parts of a bra are responsible for providing those forces. In Part 2 I introduced the concepts of stress and strain, and applied these and part 1’s principles to the design and…

Necklines always cutting in? Why full cups may be your foes and power bars your unlikely friends
I have a series of posts about the physics behind supportive bras. In the first post, I described that the band should make up most of the support system of a bra – but this doesn’t mean the straps are not important. The best way to boil that post down is that the band provides…

Bra Physics Part 2: What Can We Learn about the Band?
In my last bra physics post, I described the forces involved in supporting your breasts and what parts of a bra are responsible for providing those forces. How can this knowledge inform our decisions when making or choosing bras? This post is part of a series and covers the bands of bras – just the…

5 Red and Green Flags when going for a bra fitting
Having been a bra fitter and having been to many different bra fittings, I’ve both experienced a relatively full gamut of how bra fitters can treat people and what they’re doing behind the curtain. However I also recognise that as a thin, white, young, visibly able cis woman it’s essentially impossible for me to be…

Hi, can you tell me what's that pretty green bra? Thanks in advance.
Here is a thought I would be interested in exploring: How would the opposite affect wire spring? (meaning if the…
