I am usually a 32a. i ended up with a 34 b based on sales assoc input and what was available. the 32 gave me back fat ( i do not have back fat) so she said the 34 would be better, it ran small etc. the 34 also fit ( had to be ordered and mailed) but it still gave me "flab" over the back band. comparing it to my other regular bras, i can see that the band has too thin fabric and rolls and has "harder edges" compared to wider , thicker band on my other bras. very pretty but i will be returning. sa
