Hijab wearing ladies during delivery

Ill be delivering in KKH, and my edd is in 5 weeks time. Hopefully ill be able to go natural. Specifically for ladies that wear hijab, do we need to cover up once we change to hospital gown, and in labour room and during delivery? Like wearing hijab, handsock and long pants? Or the handsock and pants are more to when we are in the ward when visitors come in ? Do you also pack extra hijab in your hospital bag? #FTM
