I wore an instant button hijab (takva) and very high socks. Even in subsidised rooms I wore a long hoodie or cardigan down. to my ankles with a hood sometimes.
Just during labour the instant hijab was a mess so i recommend wearing a breathable inner or even tudung syria (slip on).
During labour and afterwards can request for non male staff attending to u and they will stick a sign on ur curtain. so make sure have ur instant hijab near u, sometimes the medical officers or rounding gynaes are male too.
