The thing I don't understand about bras is... The difference between US and UK sizes and brand sizing variation.
US and UK sizing refers to whether the bra was made by a company using the US or UK size system, NOT whether it was bought in that country. The big UK brands like Freya, Panache, Elomi, Curvy Kate and Mimi Holliday use the DD, E, F, FF, G, GG, H, HH, J, JJ and K cup sizes. US brands like Playtex, Victoria's Secret, La Senza and Additionelle use the US size system D, DD, DDD, G, H, I and J - the US brands tend not to go beyond these letters.
When you line up the two systems next to each other you can see how your UK size translates into a US size and vice-versa:
The reason there is fluctuation in size between brands (and between styles for that matter) is the same as why there is size fluctuation in sizes in clothing and shoes. There is no standard as to which machines are used to create a bra (and many items are still made by hand) so there is no way to produce a single 32F or 40GG size across the globe. Add to this the fact that different cup shapes alter the fit dramatically (a shallow 32F style will work on a woman with shallow 32F breasts but not on a woman with top heavy 32F breasts) and the materials used to create the bra will alter the fit (firmer materials give a smaller fit, stretchy fabrics, a more generous fit).
The thing I don't understand about bras is... Why they can't build ones that actually fit comfortably.
Remember that a lot of bras will never fit you and will never feel comfortable so if that sounds like all the bras in your drawer then you need to start narrowing down whether it's because the wires are too wide/narrow, the cups too tall/short, the band too big/small etc. Try our Bra Audit to get you started.
The thing I don't understand about bras is... Why some women simply refuse to wear the right size.
This is a complex one with no single answer. The two main reasons we encounter that keep women from well-fitting bras are they simply are not aware that bras outside of '34-42 A-D' exist or they have a preconceived idea of what bigger cup letters 'say' about a woman and their stereotypes keep them from trying a larger cup size (and usually a smaller band).
What I know for sure is that you can't rush someone into correct bra fit, they have to be emotionally ready to address this for any changes to stick.
The thing I don't understand about bras is... Why beige bras typically cost twice as much as coloured ones!
This is a great question and one I don't get asked often. Colourful bras tend to be fashion items that are created by a brand for a one off season. They are made in a limited quantity and so when a retailer gets to the end of a season and only has a few of that style left the colourful bras tend to be the ones that go on sale first to make room for the next fashion colour. Basic colours like beige and black are available from manufacturers all year round so their value doesn't diminish which is why they rarely go on sale.
I hope this sheds some light on some of your bra questions. Tune in again next week for another round of answers xx
