Rintaliivien rinnakkaiskoot / Sister sizing: a new approach

Rinnakkaiskoot perustuvat siihen, että kuppikoko ei ole mikään absoluuttinen rinnan mitta, vaan se kuvaa rinnan kokoa suhteessa ympärykseen. Tästä seikasta johtuen esimerkiksi koossa 60F kuppi on aika pieni, koska itse rinta on iso vain suhteessa ympärysmittaan. Sen sijaan koossa 100F on jo aika iso kuppi.


             KOKO 70D
             SIZE 32D

             KOKO 90D
             SIZE 40D

Koska kuppikoot ovat suhteessa rinnan alta mitattuun ympärykseen, voi nainen löytää itselleen muutaman sopivan kuppikoon vaihtamalla ympärysmittaa. Usein neuvotaan, että jos kokosi on vaikkapa 85G, rinnakkaiskokosi olisivat 80GG (tai EU-koossa 80H) ja 90FF (tai EU-koossa 90F). On kuitenkin muistettava, ettei suurempi rinnanalusmitta lähes koskaan tuota parempaa tulosta. Toisin sanoen 85G:n hyödyllinen rinnakkaiskoko on tämän yleisen ohjeen mukaan 80GG (UK) tai 80H (EU).

Lumingerien blogista löysin kuitenkin toisenlaisen ohjeen. Sen mukaan 80GG olisi liian pieni kupista, koska oikea rinnakkaiskoko olisikin kaksi kuppia isompi. Tällöin 85G:n rinnakkaiskoko olisi 80H (UK) tai 80I (EU). Tässä taulukko, joka kuvaa rinnakkaiskokoja. Katsot vain oman kuppisi mitat taulukosta, siirryt pienemmän ympärysmitan sarakkeeseen ja katsot koon, jossa on samanlaiset senttimetrimitat.

In English: The sister sizing is based on the fact that cup size is relative to your band size. I've heard that if you go one band down, you should go one cup up. This is also the advice I've heard from many blogs and it seems to be a very common one.

Here's something new: the chart above shows, that the proper way to find your sister size is to go up two cup sizes when you go down one in the band. Are you familiar with this or do you have experience in the one-cup-up sister sizing not working?


  1. I've never heard that before, but I guess it would makes sense, since back sizes are per two inches are cup sizes are per one inch!

    1. Thanks for the info! I've no idea about how the bra-sizing works in detail, but nice to hear about someone who does. :-)

  2. It does make sense. However I experienced that when you really just switch one band size for _most_ women just switch one cup works a lot better than two cups.
    We discussed this subject a lot, but we couldn't really find an answer...
    There are always exceptions, but most of the time the one cup theory works better.

    I would really love to know why. Because the two cup theory sounds so much more logical^^

    1. Thanks for the comment! This is a very interesting topic to me, because I've NEVER read about this before. It seems that theoretically the two-cups-up should work better as it's based on pure measurements, but somehow the one-cup-up works in many cases. This also explains why none of the lingerie bloggers have paid attention to this before.

      I think that the reason why the one-cup-up works may be because the cup fits a lot better when the band is tighter. I think that the breast is somehow using the space in the cup more effectively when the band is tighter and that's why it can be enough. Does that make any sense?

      I really don't know, but that's just guessing from my own experiences and from the pictures I've seen...

    2. It does make sense, but it's still strange that it works when switching to a looser band too most of the time^^
      Well, mystery, mystery ;)
