Yesterday, Ashley Graham posted an Instagram gallery with several pics and video clips of herself posing in lingerie, and captioned it, “Happy International Lingerie Day!” If you somehow overlooked this worldwide holiday and forgot to frolick in your underwear all day, you’re not alone. A website that specifically tracks social media mentions of holidays says “National Lingerie Day” was celebrated for the first time in 2015, and had only a few hundred mentions this year. So it hasn’t exactly taken off. Whether it’s a real holiday, and whether it’s national or international or what, the point is, it inspired Ashley Graham to pose in lingerie, and that’s really a celebration in itself.

Happy International Lingerie Day 💋

But this isn’t just an act of kindness on Graham’s part. She has been designing lingerie for Addition Elle since 2013, and her 15th collection with the brand is out now. She models more pieces in this gallery:

Last year, Graham celebrated the lingerie-themed holiday with a video of herself wearing another Addition Elle set:
