Yes

Choir robes were not worn when I attended Tridentine mass before the Vatican II council. They are more a feature of Protestant Sunday services.

But clerics and other prelates wore elaborate liturgical vestments -- cassocks, albs, tunics, surplices and chasubles -- as they still do today when celebrating.

You should as someone from the following orders:

The Institute of Christ the King Sovereign Prince

or

The Priestly Fraternity of St. Peter

These 2 orders celebrate the Tridentine Mass.

Also, ask a priest who was conferred the Sacrament of Holy Orders prior to 1963 (or so)...They'll know!

Generally, priests face the congregation during Mass except in those parishes that still observe the Latin Tridentine Mass where the priest faces the tabernacle and has his back to the people.

Latin was the primary language of the Mass in the Roman Catholic Church until the Second Vatican Council in the 1960s. This was known as the Latin Mass or Tridentine Mass. After the council, the Mass was translated into local languages to make it more accessible to the faithful.
