There are some days in life when you can't help but think you're having a really good boob day – those rare occasions when they're surprisingly perky, fit perfectly into a bra or do what they're told to when crammed into an unflattering sports top at the gym.
However, if you're Kendall Jenner – a woman who openly confesses to having the occasional 'good boob day' – sometimes you have to confirm your wardrobe does your curves justice, with your closest friends.
What are friends for, right?
According to US Weekly, the 21-year-old has taken to her blog to describe a day last summer when she needed to ask for the go-ahead for a bold outfit choice with her two best friends.
'My shirt was see-through, so I took this photo and just texted it to Hailey [Baldwin] and Gigi [Hadid] before I left to meet them and was like, 'Is this too much?' They wrote back, 'It's kind of a lot, but if you're into it, go for it!'
'Later, we were photographed by the paps when we were walking around the city and the internet freaked out about how see-through the look was,' she admitted, referring to an image that saw the model wearing a see-through black top.
Despite the photograph, she later decided to post a picture of her chest to Instagram, using pizza emojis to cover up her nipples.
She explained: 'As far as the pizza emojis go, when I decided to Instagram the picture, I could've covered my nipples with anything, but I chose them as a little nod to Pizza Boys (the DJ/friend group I'm part of).'
'I don't know if you can relate, but I just felt like I was having a really good boob day, lol. Do you know what I mean? Your boobs go through phases and on this particular day, I felt like they just looked nice! :),' she added.
If you got it, flaunt it, Kendall.
