The Body in retro style I find super cute. Even after many washes it retains its shape and there are no faults occurred, the snaps look like on the first day. Our Body in 74/80 is rather large in, so actually rather 80. In general it is rather less elastic, which means that it keeps its shape. The sleeves are for our son not to narrow, but it is also quite thin, it fits the Bosy well without it "starves" looks it.
