5 ways to know your bra fits you!

As part of my job as a Sales Advisor, I have been trained to do bra fittings. Luckily, my Mum has always told me her tips for making sure your bra fits, and now I’ve been given even more while I was trained. However, not everybody knows how a bra should fit, or if their bra does fit.

Over the past few weeks, I have had my eyes opened as to just how many women are NOT wearing the right bra size. Some women just don’t have a clue when it comes to bras. They size up because they don’t know how they should fit, but then don’t get the support they need and end up with back pain.

“Give a girl the right lingerie, and she can conquer the world”

It is so important to wear the right bra size – wearing the wrong size can not only be very uncomfortable, but it can cause back pain. Wearing the right bra size can massively improve the shape of your bust, and consequently, boost your confidence!

This is why, I wanted to share with you the 5 things you can look for to know your bra fits you properly.

TOP TIP: Your bra size can change depending on the style and brand so you definitely need to try every single bra on before you buy it! Last week I bought two bras that fit perfectly but they were slightly different sizes – that’s normal!

Back Size

There’s 2 things to look for when it comes to finding the right back size.

Firstly, if your bra rises up at the back, it’s too big. This is a major mistake that so many women are making. They think it’s too small, so go up another size!

The bra should be at the same level all the way round your body.

The next thing to do is to see if you can comfortably fit 2 fingers in-between the bra and your back. If there’s loads of room, it’s too big. If you can’t fit 2 fingers at all, it’s too small.

TOP TIP: I recommend getting someone else to look for you, preferably a trained bra fitter as they know what they’re looking for.

Cup Size

To get the right cup size, you need to make sure you have pulled your boobs into the bra fully. What I mean is, when you have the bra on, put your hand inside the cup and pull the outside of your boob inwards. This makes sure that you are fully enclosed in the cup and nothing is spilling out!

Next, make sure that there is no gaping at the top of the cup. If there’s a massive gap between your boob and the bra, the cup size is too big. If you’re spilling out of the cup, the bra is too small.

TOP TIP: Your bra should sit as a smooth line against your chest, with no gaps or spillage.


This one is always missed – women always seem to have the straps too loose or too tight. Just tweaking the straps can make a huge difference to the fit of your bra as well!

You should be able to fit 1 finger underneath the strap all the way around. If you can’t, you need to loosen the straps slightly. If you can fit more fingers, you need to tighten the straps.


Once you have what you think is the right sized bra on, ask yourself these questions:

  1. Is the bra pinching or rubbing anywhere?
  2. Am I getting the right support that I need?
  3. Can I imagine myself comfortably wearing this bra all day?

TOP TIP: If you’re wearing the right bra, after about 10-15 mins you shouldn’t be able to feel it. If you are aware of your bra throughout the day, chances are, you’re not wearing the right size.

I hope these tips have helped you find the right bra, but if you aren’t sure at all, I really recommend going and getting a proper bra fit. Wearing the wrong sized bra can cause a lot of pain so it’s worth spending the time to get the right one. Ideally, you should get a bra fit every 6 months to a year.

Do you know if your bra actually fits you? Here are 5 ways to know that it does!

One place where I recommend going for bras and bra fitting, is Bravissimo. They cater for women with bigger boobs and actually have really pretty bras. If anyone else has big boobs, you will know the struggle for finding pretty bras that still give enough support! Bravissimo also have an online bra fitting guide that is really useful if you’re unsure.

I really hope this post has been helpful, and I would love to know your experiences with bras!

Do you confidently know what size bra you wear?

Until next time,

    Great tips! When I was younger I wore a C cup bra, only to be taken to Bravissimo for the first time where they told me I was actually an H cup. Mortified doesn’t even cover it! I now only buy from bravissimo, as they are the only ones I feel comfortable with and there’s not much out there for the bigger ladies!
