DescriptionI bought this bra in a 36 band, rather than the 34 I usually wear, to get the cup size I needed, Here is a perfect example of a band that needs to be tighter. You may not see what the problem is until you go to the next picture and see it fastened on the tightest hook.
This shows how much a too large band can affect our appearance, including having more of the dreaded back fat with a too loose band (I'm cringing as I point this out, as I don't really want you noticing my back fat! ~ but it is true!) Importantly, it also is a big factor in how comfortable we are throughout the day while wearing it. A band that is too large will allow the straps to keep slipping down off of our shoulders as the day wears on. (I hate that!) This is due to it riding up in the back.
This bra also appears to be a little large in the cup, but it is a cotton bra, and the cups did shrink a little with its first washing (It was brand new here in the photo).
