Vogue Williams shows 'the reality of wearing really tight dresses' with honest underwear picture
Even Vogue Williams is partial to wearing a pair of Spanx on a night out.
The model and DJ shared a photo to Instagram on Wednesday of her posing in her underwear.
Wearing a black strapless bra and a pair of tummy-tucking underwear, Vogue (31) said it is "the reality of wearing really tight dresses."
The picture appears to be from the L'Oreal Colour Trophy Awards earlier this month, at which Vogue wore a sheer Paul Costello jumpsuit.
The Dublin native, who is in a relationship with Made In Chelsea star Spencer Matthews, recently revealed that she is considering freezing her eggs.
"I have been hearing the tick-tock of my biological clock and I decided it was time to do something about it," she wrote in her Sunday World column.
"Recently I have heard so many stories from couples unable to conceive, friends not being able to have children at all and other people turning to IVF for help.
"These are all people of my generation and fertility is a huge issue for so many of them."
Vogue said that while having children is something she wants "more than anything in the world", she admits she wants a career too and that has been her "priority" thus far.
"Having children won't be something I will miss out on. It's too important to me," she said, adding, "It's just that I don't feel I'm ready yet. I feel like I have so much more to achieve professionally, but when will it be too late?"
Vogue split from her husband Brian McFadden in July 2015 after three years of marriage, and she revealed she considered she may have to go it alone with regards to having children.
"When I found myself single after two long-term relationships, it did cross my mind that I might have to go it alone if it was something I wanted," she wrote.
"If children are what I really want for the future, the first step for me was to see how fertile I was.
"I may never need them, but I don't plan on having children for a few years and after that time my eggs won't be as good as they could potentially be now."
