The venue is booked, the catering and flowers are done, the guest list has been sorted with only a minimum of angst and - above all - you have found THE dress.
Now imagine, as a bride-to-be, being told that the wedding dress you love is actually going to cost you £463 more than normal.
Why? Because it's not available in your size.
This was the annoying realty facing Mary Jane O'Toole.
Since her fiancé had proposed to her in December 2016, Mary Jane had been steadily losing weight.

"I had a pretty good idea I didn't want to be big as a bride. Growing up I told myself, you're not going to be a fat bride," she told the US TODAY show .
"But I don't want to take away from anyone’s experience being a plus-size bride. Every bride is beautiful."
Mary Jane's motivation wasn't just about how she looked and felt about herself, it was also prompted by years of having to deal with the "fat tax" - the term she uses for plus-size clothes often costing more.

Following their engagement, she and her partner started using a fitness app and began to monitor their diet .
She was what she calls a "street size 12" by the time she was dress shopping and found her perfect dress.
Because the dress didn't come in her size, Mary Jane was told it cost $600 (£463) more to make.
While the bride-to-be loved the dress, she refused to pay such a large amount extra and instead upped her exercise regime, training up to five times a week.

By the time her November 19 wedding day came around she had already lost a very impressive 61kg. Not only that, but she'd also found another perfect dress - and looked incredible in it.
"I can't believe how different I look from one October to the next," she wrote in an Instagram post shortly before her wedding.
In a post from her actual wedding say, she wrote: "I'm in a dress I NEVER thought I would be able to wear."

As well as being proud of what she's achieved, Mary Jane also wants to see fairer pricing of plus-size clothes.
"Big girls want to look good too and it doesn't help our self esteem to go into a store and not find our size," she explained to TODAY.
"Women spend money. If most of the female population is plus sized, wouldn't you want to accommodate the people who want to buy your clothing?"
