I’ve lost count of the number of conversations I’ve had at events or in my sweater fitting classes that went something like this:
Knitter: “So the pattern is sized by full bust measurement?”
Me: “Yes, but if you’re larger than a B-C cup you will probably need to make the size that’s closer to your high bust measurement and maybe add some extra room with darts at the bust.”
Knitter: “Right, but I’m just an A cup so I don’t need to worry about that. But I’m confused because you said full bust measurement wasn’t my bra band size and I wear a 36A and my full bust measurement is 36 inches.”
Me: “Uh, are you sure you’re wearing the right bra size. I really don’t think you’re an A cup, I’d estimate that you’re closer to a 32D.”
Knitter: “OMG but a D cup is HUGE!”
Me: “That’s what the media would have you believe, but go get fitted and get back to me.”
2 weeks later via twitter –
Knitter: “Wow, you were right! My clothes look so much better now and my bra straps don’t fall down.”
I’m not relaying this story in a clumsy attempt to make myself sound smart but in the hope that it might help some of you make sweaters that you’re proud of and that make you look and feel awesome. Although after helping so many people try on sweaters and measure themselves it appears that my only possible future employment (sometimes I freak out about how unemployable I’ll be if people stop knitting so please don’t do that!) will be as the strict lady in the bra shop that takes one look at you and reels off a number.
Anyone who’s taken my Perfect Sweater class knows that the section on taking measurements begins with two rules:
– Have someone else take your measurements. Seriously I know it’s tempting to do yourself but if you can accurately measure yourself you’ve also figured out how to clone yourself and should probably stick with being the evil mastermind you obviously are and not worry too much about making a nice sweater. My favourite illustration of how you can’t even take simple measurements of yourself accurately is that if you put a tape measure around the fullest part of someone else’s bust, hold the tape measure loosely in place and then ask them to lower their arms the tape measure will slide further out. And, unless you always walk around with your arms sticking straight out from your sides you want the second measurement. Try taking that yourself.
– Wear the undergarments you’re going to wear with the sweater. Whether that means a push up bra, a light sports bra, a retro bullet bra, a prosthetic, nothing at all, or a binder, I don’t care but it’s going to change your overall shape, possibly including things like posture. This is different from considering the layers you might wear under something like a jacket, which can be considered when adding ease for a particular garment. If you do prefer to wear a structured bra and are not absolutely, perfectly certain that you’re wearing a well fitted bra go take care of that before proceeding to take any measurements.
It seems like the people with a vested interest in doing research on this subject are the same people who want to sell more bras but I’ve seen figures as high as 80 – 90% of bra wearers are wearing the wrong size. Given how different all of our bodies are (if you really want to see how true this is this gallery of breasts of all sizes and agesdoes a good job of showing how much variation is perfectly normal – obviously NSFW!), how random sizing can be between brands and styles, and how even the same body does not stay the same from 1 breast to the other or through the whole month it seems pretty hard to really quantify. There’s no shortage of anecdote (and I obviously have plenty of my own) that does suggest that large numbers of you are not really the size you think you are and that the more likely scenario is that you’re wearing a band size that is too large and a cup that is too small.
Cup size is proportional to band size – ie. a 36D is more or less the same cup as a 38C you may actually be wearing the correct size cup, but once you go down in band size the letter will get larger (uh, not that letters get larger, but you know what I mean!). One major reason for this is that there isn’t a very clear methodology for measuring your body and choosing a size, but what really doesn’t help is that the vast majority of sources give a very out of date formula that might have worked when bras were made from less elastic materials but certainly isn’t appropriate today. Any formula that tells you to measure around your underbust and add 5″ is going to cause exactly this problem.
How can you tell you might be wearing the wrong size? First of all, if you used any formula like that above. But most obviously, you’re probably uncomfortable. The band riding up or sliding around in any way is an indication that it’s too loose, and since the band will stretch out over time it should be initially snug on the loosest hooks. If it’s cutting in uncomfortably though it’s too small or sitting in the wrong place on your body. If the cups cut into your breast tissue anywhere or some is spilling over the top when they’re either the wrong size and / or the wrong shape – spacing also makes a big difference. If the straps keep sliding down your shoulders unless you tighten them so much they leave dents that’s a sign again that the band is too wide, not that you just need to get used to the straps being tight – they’re sliding off because they’re too widely spaced. When taking measurements flags such as a reasonable difference between high and full bust measurements, other measurements corresponding to a smaller garment size than your full bust would indicate, a difference of more than 1-2″ between front and back shoulder to underbust lengths, are a good indication that you should be a wearing a bra with a cup size larger than B-C and that if you are not it might be a good idea to get fitted.
So can you calculate your bra size from your measurements? Not really, no, but you can get a good indication of whether the size you’re currently wearing is wildly off and find an estimated size to start trying on. Because of all of the aforementioned factors, finding a good fit is a combination of size and particular bra, so there’s really no substitute for trying on and it helps to know what a good fit actually is which is where experienced fitters can be so helpful. This Ravelry page has a pretty good guide to use as a starting point and these guides on Bravissimo and Figleaves may be helpful too.
The best idea is to get a fitting from someone who really knows what they’re doing – which obviously will not be everywhere that offers such a service. Look for a store that actually sells a full size range, in a selection of different styles – if they don’t sell at least a 28 band and cup sizes up to G (not the largest available just an indication that the store has some idea of what they’re doing) then they’re just going to try and sell you something that they stock, regardless of fit. If you can, bug everyone you know and find that magical fitter that can tell you instantly what size and style to start with, but larger chains that have fitters I’ve heard positive things about are Nordstrom in the US, and Bravissimo in the UK (solely for cup sizes above D). If you are looking for harder to find sizes both Bravissimo and Figleaves ship internationally and there are also many smaller online sellers that specialise in particular fitting areas and have reputations for great customer service, it would be extremely helpful to everyone if you could leave your personal recommendations in the comments. Wearing a bra that fits well won’t change your life, but if you were previously wearing one that didn’t it will make you a lot more comfortable and you’ll be ready to take measurements and make a wonderful sweater.
If you want to talk about breasts further, figure out bras that might work well for you and discuss fitting sweaters around your breasts the Ravelry group The Bustline that I linked to above for info on measuring might be just the place for you. I know reading posts there has been helpful for me in figuring this stuff out and thinking about the fitting issues different knitters will have when they knit my patterns. There’s also the less active Itty Bitty Titty Committee, obviously a group for the smaller breasted.
Introducing the first in an ongoing series of guest posts. I'm honoured that we're beginning with this vital letter from Emi Ito.
Emi has been outspoken about the cultural appropriation of the kimono in fashion and has helped many makers and designers find a less hurtful approach to naming their patterns and products.
