Parade sports bra 2+

brand new sport bra in blue green color from parade. cool cut out effect on bra. bra is called "longline cutout" size 2+. note that the garment itself says "2". my understanding is that the plus range comes in numbers while the traditional range comes in SML type sizing, see chart. I bought it final sale but it doesn't fit. I've only tried it on once. it's otherwise new, but it didn't come with tags so I don't want to list it as "new with tags" I have 2 others for sale too! bundle to save!
