Understanding The French Bra System

When it comes to buying lingerie, understanding the French bra system is key. The French bra system has a unique sizing system that is different from the American sizing system. It can be perplexing if you’re not familiar with it. To make sure you get the perfect fit for your lingerie, here’s a comprehensive guide to understanding the French Bra System and how to choose your cup size.


The first step to finding the right cup size is measuring yourself correctly. To measure your frame size, wrap a tape measure around your ribcage just below your bust line. Frame sizes typically range from 26 inches up to 46+ inches. To measure your cup size, wrap the tape around the fullest part of your bust and use available cup size charts online or at lingerie stores to determine what letter corresponds with that measurement. Most brands only offer up to a DD or G in their product lines.

After finding out what letter corresponds with your measurement, you will have an idea of what type of cups would be suitable for you and can begin shopping! However, keep in mind that there are also “sister sizes” which are bra sizes that have the same cup volume but different band sizes (for example 36D & 34DD). These sister sizes can also work for some body types as long as they fit comfortably on both sides without pinching or pulling too much fabric away from where it should be placed alongside one’s body.

Finally, when trying on bras always remember: Comfort is key! Make sure it fits well on both sides without any pinching or pulling fabric away from its natural position against one’s body before making any purchase decisions. With this knowledge about how the French Bra System works and how to find out which cups suit you best; getting fitted for perfect fitting bras won’t be difficult anymore!

Comparing European And US Bra Sizes

Comparing European and US Bra Sizes is becoming increasingly important to understand in the lingerie industry. Many consumers are unaware of the differences between US and EU cup sizes, as well as how to accurately measure their bra cup size according to their body shape. It is also significant for customers to be aware of common sizing issues and how trends in the lingerie industry can affect new styles of bras. Let’s take a closer look at all these topics so that you can make sure you get a properly fitting bra!

Understanding the difference between US and European cup sizes is key when shopping for a new bra. Fortunately, using the above bra size conversion chart makes it easy. First, check the US cup size of the bra you already have and are comfortable in – this will be your starting point for finding your conversion size. Then, use the chart to find that same cup size under the US column. Finally, locate your corresponding EU cup size in that same row under the Europe column on the right-hand side of the chart.

Plus-sized bras have a band size of 38 or larger, while full-figure bras encompass sizes DD+ with a 38 or larger band respectively. Both require specific measurements due to their wider circumference sizes than regular cups (32-36). It’s also important to know that bra sizes work in ratios, where the volume of the cup varies with different band sizes depending on how large or small they are relative to each other. For example, if someone wears an A-cup but requires some adjustment due to too large/small straps or cups being too tight/loose, they may require finding a different band size which can be found by ‘bra sisters’. Knowledge about how these different elements work together helps determine the best fit for an individual’s own needs when selecting their next perfect lingerie set!

Differences Between American And European Bra Cup Sizes

If you are shopping for bras, you may notice differences between American and European cup sizes. Understanding how bra cup sizes work can assist you in finding one that fits perfectly. To ensure a proper fit, it is essential to measure for the right size and style of bra. Here, we will discuss how to measure for the correct bra cup size and the differences between American and European sizing systems.

The size of your bra consists of a band size (the number) and cup size (the letter). Band sizes range from 26 inches to 46 inches or more in the US/UK system, while other countries use different measurements such as 75-105 in France or 60-120 in most other countries. Cup sizes depend on both the letter (32C, 34C, 36C) and band length – when it comes to European sizing systems they range from AA – J, with some countries having even larger cups available up to KK+. It’s also worth noting that bra sizes with the same cup volume are called sister sizes; knowing your current sister size allows you to switch effortlessly between US/UK band lengths as well as international measuring systems when purchasing bras.

When measuring for your ideal fit at home, make sure: 1) You take two measurements – around the fullest part of your bust line & underneath your bust line – then add 4-5 inches depending on where it falls on a standard US/UK chart provided by many lingerie stores; 2) The difference in inches corresponds to a cup size; 3) Choose a style of bra that best fits your body type; 4) Avoid common mistakes like wearing too small or too large bands or straps; 5) Understand how a perfect fit should feel – snug but not too tight! 6) Lastly remember proper care is essential so wash according to instructions & store properly away from sunlight to maintain its shape over time.

By understanding these differences between American and European sizing systems when buying bras online or offline, you can ensure an optimal fit every time.

Finding The Right Fitting Bra For You

Finding the right bra size can be a difficult and confusing task. Knowing your bra cup size is an essential part of finding the perfect fit and style for you. In this section, we will dive into what bra cup sizes mean, how they are assigned, and tips for measuring yourself to get the perfect cup size.

Bra cups are classified by letter (A-K) according to their relative volume compared to band size (A being smaller than B, etc.). Cup size is determined by subtracting the band measurement from the bust measurement—a difference of 1” corresponds with an A-cup; 2” with a B-cup; 3” with a C-cup; 4” with a D-cup; 5” with a DD/E-cup; 6″ represents an F– G– or H–cup; 7″ stands for I– J– or K–cups.

To get started on finding your own ideal bra cup size, first measure your bust size and band measurement. To measure your bust correctly, take a measuring tape around your back at band level (the area just under the breasts), making sure that it is parallel to the floor all around. Measure it in inches over the fullest part of your chest—this will give you an accurate measurement for both cups and band size. Subtract this number from your bust measurement to determine the difference between them, which will give you your true cup size!

It’s also important to remember that different brands may run smaller or larger than normal, so knowing about sister sizes can help you find ones that fit even better! Sister sizes refer to two different sets of bras where one set has larger cups but smaller bands while another set has smaller cups but larger bands. For example, if you wear 36B but feel like it’s too tight, then try going up in sister sizing like 34C instead – same volume just slightly different shape! Knowing these tricks can help make sure that no matter which brand or style you choose, there will always be something perfectly suited just for you!

Different types of bras have various benefits, so it’s best suited according to personal preference such as demi cups provide less coverage whereas full coverage bras offer more support throughout day-long activities – combine all this knowledge together along with finding correct measurements using the above steps & voila!
