I bought sports bras from Motherhood Maternity when I was pregnant and I wear those all the time. Super comfy. Haven't used my other ones yet, but I recall my Target one being tight in strange places too.
Possibly overkill because I was a DD before pregnancy and now hanging out in G territory but I am all about my Shock Absorber bras. It keeps them in their place.
This! Just a few more cup sizes and it's me. They are amazing!
