Chapel veils – lace veils, commonly black or white, which can vary in size and shape – are worn by women when entering a church, or anytime in the presence of the Blessed Sacrament. Traditionally, married and widowed women wear black veils, while young girls and unmarried women wear white or off-white veils.
However, the color choices are not a hard and fast rule.

Veiling Options for Women and Girls
There are various options here for women:
the classic Catholic lace mantillas
lace chapel caps (this is for young girls)
oblong gauzy or cotton scarves worn over the head and over one or both shoulders, or tied in various ways (see this page for information on various ways of tying scarf-type headcoverings (offsite, will open in new browser window)
standard-sized square chiffon or cotton scarves folded into a triangle and worn tied under the chin in the Jackie-O style or tied behind the head in the peasant style, etc.
large square scarves worn “babushka” style (fold large 36" square scarf into a triangle and place over head with the “tail” side hanging down in back. Then turn back the pointy ends behind the head and tie into a bow or make a knot over the “tail”)
shawls worn over the head
elegant but simple hats (cloches, toques, berets, “Lady Diana” hats, etc.)
Traditionally, single women wear white or ivory headcoverings, and married or widowed women wear black, but this isn’t a hard and fast rule, and is often ignored.
