Why we can't stop staring at pictures of women and their 'saggy boobs' on Instagram.

In our minds, we know breasts come in a myriad of shapes and sizes.

We know women use tools to make their boobs sit how they’d prefer they did on their own.

Bras, push up bras, strapless bras, chicken fillets, stick on bras, double-sided tape, duct tape, Facetune, Instagram filters, cosmetic surgery…

We also know some women have breasts that naturally sit up or look full and round, just the same as some women are short, some have long legs and others have skin that browns nicely after a summer in Europe.

But a leisurely scroll through your Instagram feed can sometimes make you and your boobs feel like the odd ones out.

If you’ve ever looked in the mirror or fondled your breasts before bed and thought, ‘does anyone else have boobs that look like mine?’, there’s an Instagram movement that will help.

It’s called #SaggyBoobsMatter. Go on, have a look.

your mcm’s worst nightmare

Plants are friends.???? Having plants ???? can be super therapeutic. Also vegetables and fruits are so good for feeling better internally. As someone who admittedly could eat better overall and has IBS, I’m always reminded of how important it is to incorporate plants – in all forms – into my diet, living space and for my pain management.????????????. . . #cannabiscommunity #effyourbeautystandards #bodypositive #bodypositivity #fatgirl #SAGGYBOOBSMATTER #ibs #houseplants #plussize #greenhouse #710 #sundayvibes #cbd

Long before unknowingly starting the hashtag movement, Instagram influencer and author Chidera Eggerue told her mum she was going to get a breast augmentation the minute she turned 18.

“I told my mum: ‘When I turn 18 and get a job, I’m getting a boob job’… I just thought: ‘I’m going to get a boob job and then I won’t be sad about my boobs any more,'” the now-23-year-old told The Guardian.

She’s not alone in having that thought – women have been feeling this way about their ever-changing bodies for decades, but only now in 2018 is it conceivable that a teenager would undergo plastic surgery to enhance their appearance.

We know one in four young people have serious body image concerns, with girls aged 15-19 being the most at risk, The Butterfly Foundation reports. Thanks to an investigation by ABC’s Four Corners, we also know more of those young people are getting cosmetic procedures than ever before and posting images of the ‘after’ results on social media.

In contrast to what she was seeing on Instagram, Chidera decided to post a picture of herself wearing a yellow dress on a night out. She also happened to not be wearing a bra, and for some reason she can’t remember, she told Mashable, the south Londoner captioned the image #SaggyBoobsMatter.

Although she knew her breasts looked ‘saggy’, she wanted to get across the message that your value isn’t determined by your cup size.

“First of all saggy boobs aren’t even represented at all. And secondly, most women have boobs that aren’t perky. That means there’s a whole conversation that needs to be had about women’s bodies, and more importantly how we see our own selves,” she said.

“Women are taught that our value and our ability to be loved is wrapped around how appealing, attractive, and desirable we are. That idea is so flawed. Being worthy of love is nothing to do with what your body looks like. It’s literally the least important thing.”

57 per cent of girls compare themselves to other people on social media. Here are some tips to help your daughter (or yourself) with body image. Post continues after video.

The hashtag is encouraging other women to post images of themselves and their breasts, exactly as they are. Some are taken just before bed, or how they intend to leave the house. Some women are in their early 20s, some have had kids and have breastfed. Others have experienced growth spurts or gone up and down in weight throughout their lives.

All the ways these factors affect how our breasts look are completely normal, but as Chidera said, what we see around us becomes our reality. If we see more bodies that look like ours, or the person’s next to us, or women we’ve never met on social media, the easier it is to look at our own through a kinder lens.

Movements like this one don’t demand every woman put up a photo on Instagram of their boobs without a bra on.

But they do ask us to broaden our ideas about what boobs can look like.

Does seeing images of other women of different shapes on social media make you feel better about your own body?
