When you try on a bra from a brand you haven’t tried before, you might find that your usual size doesn’t fit quite right. If you’ve had this problem before, AmpleBosom is here to help. We’ve put together a size chart to help you find similar bra sizes for you to try. In this blog, we’ll be looking at sister bra sizes for a 56 band size.
What Are Sister Bra Sizes?
If you are finding that your usual bra size isn’t fitting correctly, this could be down to any number of reasons; a different manufacturer, a different brand, or a different style of bra. Any of these reasons may mean you have to look for a different size of this bra.
Sister bra sizes are the sizes that surround your bra size. It’s good to know what your sister sizes are, so you can try these on if a new bra isn’t giving you the usual amount of support and comfort.
You can read more about this in our What Are Sister Bra Sizes? blog.

How to Find Your Sister Bra Size
So, how will you know which sister bra size you need to choose?
When you’ve located your current bra size on the chart, you’ll be able to read across and discover your sister sizes. There is an option to size up, if the bra you’re trying on feels too small, and an option to size down, if the bra you’re trying on feels too big.
If you go up in band size, you may need to go down in cup size. If you go down in band size, you may need to choose a higher cup size. This is just a guide - please note that sister sizing can be quite complicated as you may need to adjust both the cup size and the band size to get the best fit.
Sister sizes can be other sizes that surround the initial size. Take a look at our example chart based on UK sizing.
