Ashley Graham gave fans a sultry glimpse of her rarely seen tattoo as she posed for a playful underwear selfie. 

The 28-year-old plus-size model from Lincoln, Nebraska, took to Instagram on Tuesday to share a photo of herself modeling a pair of black lace underwear in a bathroom in San Francisco, giving her 1.7 million followers a peek at a portion of her tattoo, which remains mostly hidden behind her skivvies.
