1. How To Choose the Right Bra Size

    Chances, are, by now, you think you know your bra size. But when did you last get measured, or measure yourself?

    We've all heard that up to 90% of women are wearing the incorrect size, which, given the implied health risks, is a little concerning.

    Even a little weight loss or gain can affect which size you are, and with very, very few people remaining the same size and shape for their entire adult lives, chances are you could have changed and not even noticed. We recommend checking your bra size at least once a year.

    Luckily, you don’t need a professional lingerista to burst into your house, waving a tape measure: we’ve got some expert top tips right here to allow you to do it yourself, simply and easily.

    Above: Find out how to find your bra size at home in this video from lingerie expert, Sammi Cole.

    How to Find Your Bra Size

    Before you start, you’ll need to grab your most comfortable bra (as chances are, this is the one that fits you best), a soft tape measure, and a mirror. Make sure that the bra doesn't have any extra padding, as this could falsely affect the reading.

    • Standing in front of the mirror whilst wearing the bra, pass the measuring tape around your back and pull it firmly (but not tight!) against the skin just beneath your bust, where the underwiring usually sits. Check the measurement in cm, then check the table below to find your body size. For example, if your underbust is 75cm, you will fall within the 72-77cm range in the table below. Therefore, your corresponding body size will be a size 12.

    • Next, move the tape measure up to the fullest part of your bust, keeping it against your body without it digging in, and read the measurement in cm. Use this figure, coupled with your body size, to determine your cup size, based on the table below. For example, if your bust is 96cm, and your body size is 12, you will fall within the 95-97cm bust range, for size 12, in the table below. Therefore, your corresponding cup size will be Cup DD.

    • Your bra size is your body size and cup size. So in this case it would be a 12 DD.


    Non-Cup Sized Bras

    Sometimes, you may come across bras (particularly in sets) that are sized by dress size, or Small, Medium, or Large rather than cups sizes, and this can get a little confusing.

    On Lovehoney, all of these bras should have a brand size chart featured on the page which tells you the equivalent dress size, but not necessarily the cup size.

    So, very basically put, here is the average cup size for each UK dress size.Now, chances are, you're looking at the table above and thinking, 'Well, that's ridiculous, I'm a size 10 and I'm definitely not a 34B.' The sizes above are based on the standard overbust measurements for UK dress sizes, but this doesn't mean that the only bra size that can wear a size 10 is a 34B. This is where sister sizes come in.


    Sister Sizes

    Above: Find out exactly how sister sizes work in this video from lingerie expert, Sammi Cole.

    The volume that a bra can contain (i.e. the sheer amount of boob) is proportional to the underbust size, meaning that when you increase the underbust, you're increasing the size of the cup, even if you choose the same cup size.

    So let's say you are a 34B. If you increase the underbust size of your bra to the next width up (a 36) and decrease the cup by one size (an A), then you have what is known as one of your "sister sizes" - that is, a bra with essentially the same volume as your true size.

    This does require a degree of common sense, however: technically, a 30G bra would have the same volume as a 44A, but as most bras only come with 3 hook-and-eye positions on the back fastening, it's unlikely you'd be able to get the best fit beneath the bust. Generally speaking, you can go up to two sister sizes in either direction.

    So with this in mind, the above table can look a little more like this:

    UK Dress Size

    Average Bra Size

    4 28B/30A/32AA
    6 30B/32A/34AA
    8 30C/32B/34A/36AA
    10 30D/32C/34B/36A/38AA
    12 32DD/34D/36C/38B/40A
    14 30G/32F/34E/36DD/38D
    16 32G/34F/38E/40DD
    18 36H/38G/40F/42E
