Dear April Lynn, Glad you found this article so helpful! Sometimes we can’t escape a little back fat if we are going to get the support we need. Sometimes you can just raise or lower the bra band to cover that area a little better. If that does not work, I would consider trying a 42F (maybe find one on sale). What you will want to do is wear it for the day and see if the band 1) Lies smoothly over your back 2) slides up. If it lies smoothly and does not slide up (and you don’t come out of the cups in front), you may be able to wear the 42 band. You may have to start on a tighter hook than the loosest one. If this gives you the fit you want, that lasts all day, it may be the best way to go. Just realize that you may not get as much wear out of this bra because you will only be able to tighten it as much as the remaining hooks. But, sometimes we are between sizes and this can be the best solution. Let me know if you try this and how it works out!
