Orbis Catholicus Secundus reports that American Cardinal [Raymond]Burke celebrated a Pontifical Mass at the Lenten Stational Church of San Nicola in Carcere (St Nicholas in prison) with outdoor penitential procession and chanting of the Litany of Saints. San Nicola in Carcere is one of the traditional stational churches of Lent.
For the procession, His Eminence wore a very tall golden mitre (mitra aurifregiata), and a penitential purple cope bearing the coat of arms of Pius IX. For the Mass, he wore another tall white mitre and a purple chasuble and Pontifical gloves (chirothecœ). The use of episcopal gloves became customary at Rome probably in the 10th century. Most of these liturgical vestments have been rarely seen after the Pauline changes of the last ‘60s. The revised Caeremoniale Episcoporum no longer imposes on bishops the use of episcopal gloves.
I wanted you to see the gloves, which all too often seem to be not quite the right color and tend to clash with the other vestments. These chirothecœ are the best match I've seen yet. The vestments may seem somewhat splendiferous for the Lenten period, but think of it this way: Lent is a time of fasting, so the people who attend the services at least get to feast their eyes on colorful silk and beautiful lace during the penitential season.
Cardinal Burke explains the attraction of masses with elaborate pageantry and lavish vestments in the video below which was posted on the website of the National Catholic Reporter.
