I got sick and tired of bras 10 years ago. I hate everything about them. What I do now is buy soft, stretchy, seamless bralettes with no hooks and a bottom band at least an inch wide. Buy them in at least a size larger than the sizing guide will suggest. If it feels tight, it's too small....the opposite of what a bra fitter would tell you. The drawback is that the soft band will then bunch up under your breasts in an annoying fashion as you move about. But you can fix this, with a sewing machine, or a few stitches by hand and it just takes a few minutes to do:
Find a soft stretchy bralette that feels great when you try it on and fits the girls well. I love the Hanes Bandini bras and they are dirt cheap...about $12 for a 2-pack. They are somewhat inconsistent on band width, so you just have to look through the selection to find ones that have a one-inch wide band (some have a half-inch band...skip those).
Buy some 1 inch no-roll elastic - measure your rib cage using the elastic. Cut to size. The elastic should fit around your rib cage without digging in at all.
Cut a small slit in the outside layer of the bra hem, in the center front. Insert the elastic and work it all the way in so that it is fully inside the hem, and is not twisted. This will take a bit of patience, but you can do it.
Stitch the elastic vertically on either side of the slit, and vertically again in the center back. This way it will be anchored to the bra in three places to prevent twisting. But otherwise, it 'floats' inside the band. Since the elastic will be longer than the bra band (while it's not being worn), you want to make sure that center back stitching is done right in the middle of the length of elastic. When you put the bra on, the elastic should lay flat and smooth within the stretched fabric and leave no indentation in the flesh.
Now you have all the soft, stretchy goodness of a bralette, and a band that will lay flat and stay in place WITHOUT BEING TIGHT. The bra will look a bit funny when not being worn because the elastic will be longer than the bra band fabric. But put it on, and it's COMFORTABLE, it actually feels good to wear. I never feel the desire to take it off until bedtime, and no woman hates bras more than me. It's like the difference between a vice grip, and a gentle hug from a dear friend.
