Natalie Jade Magill purchased the navy blue dress through the ASOS website on February 15.
The slinky plunge twist front midi dress – on both the Boohoo and ASOS website – appears to protect the models’ modesty.
But when the 28-year-old tried on the dress for herself, it wasn’t what she thought it would be.
In fact, the £20 garment was “overexposed” as the split started just below her belly button.
“Where is the material?”

Natalie, from Greater Manchester, said: “I ordered it for a friend’s 30th birthday event. As soon as I had the opportunity to try it on I did and was pretty excited to slip it on.
“The colour initially looked a little different to the image but it was still nice so it didn’t put me off.
“Putting it on it felt nice but as I positioned it I knew something wasn’t quite right.
“Where is the material to cover your min? I was actually howling laughing at it and thought ‘surely this can’t be right?’
“To have something like this not fit, it just completely knocked me and meant I then had to go on the hunt for something else which is frustrating and annoying.”
During her pregnancy with her miracle IVF baby Maddox, nine months, Natalie gained 3st 7lbs.
Although the dress not fitting correctly was a blow for Natalie, the businesswoman believes it’s down to the design.
After her frock shock, the mum returned to the ASOS website and noticed that in one of the photos, the model appears to be using her hand to cover the “gaping hole”.
Natalie returned the dress and has received a full and “extremely quick” refund from the online retailer.
She said: “I went back to the original image and noticed the model had her hand across the gaping hole which now makes sense as it’s probably designed that way. But why you’d want a dress like that I don’t know.
“I returned the dress a few days later and ASOS have been extremely quick to rectify and refund.
“It hasn’t completely put me off using Boohoo as a company but I know I’m not the first to sadly have this issue.”
An ASOS spokesman is not offering a comment on the matter and Boohoo has been approached for a statement.
