I actually purchased the exact same bodysuits in pink, with no issues.  The tape they used to package these bodysuits left residue on the fabric and it would not wash out.  I use them under other clothing due to this.  It's a shame because the patterns are really cute.  Although I had issues with the tape residue, I have not had any issues with the paint peeling or separating from the decals - even after several washes.
