'''Sister sizes''' are bras with the same cup volume which could, in theory, be used as a substitite for one's true size.

One's sister size could, in theory, be used as a substitute for one's true size, but the bra wouldn't [[How-to tell if a bra fits|fit]] correctly.<ref name=wp>[http://en.wikipedia.org/wiki/Brassiere_measurement ''Wikipedia'': "Brassiere Measurement"]</ref>

Sister sizes have the [http://www.cupmysize.com/bra-sister-size/ same cup volume] as each other. The difference of band size simply changes the fit.
 
 
Typical [[Offline retailer|stores]] suggest sister sizes to sell their limited inventory to the customer, as opposed to a bra that actually fits. This perpetuates the problem of most women wearing band sizes too large, with correspondingly wrong cup sizes.<ref name=wp/>
 
 
Sometimes, two adjacent sister sizes may both fit a woman, since the cup volume is the same, while the band size can be adjusted to a small degree by using the hook and eye fasteners in the bra clasp.<ref name=wp/> However, it is usually less comfortable and flattering.

==Benefits==
 
For people whose ideal bra size is somewhat of an outlier, like 28C or 36L, using a sister size (often a larger band/smaller cup) can allow the person to wear a particular bra that is otherwise off-limits to them due to being outsized. For example, someone who needs a 28C can try 30Bs to expand their selection of bra [[Bra style|styles]]. They could then [[How-to alter a bra#Shorten band|alter the band]] or use a [[Rixie Clip]] to make the bra fit better.
 
 
Some [[Bra manufacturer|brands]], or particular styles from some brands, can run [[Bra sizing by company|smaller or larger]] than another bra of the same size. Because of this, someone who wears a size right outside the bra's size range could end up fitting into it because the bra [[Bra anatomy#Band|band]] might run a little small or the [[Bra anatomy#Cup|cup]] might run big and vice versa.

==Dangers==
 
It is not recommended to wear a bra any more than one sister size away from your ideal bra size.<ref>[http://reddit.com/r/ABraThatFits/comments/25zael/quick_running_out_to_the_store_and_i_need_to/ ''reddit'': quick - running out to the store and i need to check sister sizes!]</ref><ref>[http://reddit.com/r/ABraThatFits/comments/16xsgk/how_well_do_altered_bras_support/ ''reddit'': How well do altered bras support?]</ref> This is because, while, for example, sister sizes 34FF, 36F, 38E, 40DD, and 42D all hold the same volume, the bras are designed for very different body shapes. The higher in band/lower in cup you go, the [[Breast shape#Shallow|shallower]] and wider the cup becomes. If the bra band is altered to be smaller, the way the cup fits will change and the straps also start out further.<ref>[http://reddit.com/r/ABraThatFits/comments/1bib1o/i_think_im_going_to_give_some_homemade_bra_band/c97ad20 ''reddit'': comment by tinkikiwi in 'I think I'm going to give some homemade bra band alterations a try...']</ref> The lower in band/higher in cup you go, the more projected and [[Breast shape#Narrow|narrow]] the cups get. The more [[Bra extender|extenders]] used, the further out the [[Bra anatomy#Straps|straps]] lay, which can cause them to constantly slide off your shoulders as they now sit closer to the arms rather than the shoulder blade.
