How to tell if a calculator is inaccurate
Signs of a bad bra calculator include:
- If it tells you to measure your "overbust", or under your armpits
- If, in UK and US calculators, the band size is several numbers larger that the number you put as your ribcage or underbust measurement (ex: Your ribcage measures 38 but the calculator tells you to wear a 42)
- If, in EU/JP calculators, it says the number you measured your ribcage as is the same as your band size (ex: your ribcage measures 65cm, and the calculator says to wear a 65). The EU/JP sizing system has "plus four" built into it
