National Give Your Sister Underwear Day
What? You’ve never heard of National Give Your Sister Underwear Day? Well, we are here to change that. We want to celebrate the amazing bond of sisterhood by establishing a national holiday of recognition.

The Origin of This Glorious Sisterly Day
Spreading knicker love is very close to our hearts . . . and families! Our founder Antonia gave her sister Claudia 30 different pairs of knickers for her 30th birthday. In the spirit of the sisterly love, [ENCLOSED] founded National Buy Your Sister Underwear day on November 30—Claudia’s birthday—in 2013, so you don’t have to wait until your sister’s birthday to give her a pair of adorable knickers.
The Second Annual Buy Your Sister Underwear Day
Mark your calendars: the second annual Buy Your Sister Underwear Day is coming up on the last day of November. Whether you are giving your sister(s) a frilly feminine thong, a playful fun g-string, or a beautiful silky bikini, trust our knicker expertise.
As we like to say, friends don’t let friends wear ugly knickers. And that is most certainly true of our dearest friends, our sisters.
