"With all the planning, and after meeting with the photographer and discussing dresses with my sisters, I started to think about what my wedding photos were going to look like. Well, probably the more correct statement would be that I started to obsess over them."
This is where things started to go wrong.
Penny says she wanted her two sisters to look "as ordinary as possible".
"We're all fair-skinned and blonde, and I demanded that the bridesmaid dresses wore a neon yellow that made them look washed out and slightly ill. I told them I was going for a fun, party look but I was thrilled that colour made them both look pallid.
"But by far the worst thing I did was to fatten up my sisters in the months leading up to the wedding. Every morning I was a picture of sunshine and morning glow as I insisted on making breakfast smoothies for everyone. I told them I wanted us all to look our best on the big day, so I was making them this special slimming smoothie," she confessed.
While her sisters' smoothies had fattening ingredients, Penny's smoothie was only fruit and coconut water.
"By the time my wedding rolled around, each of my sisters had to have their dress altered to accommodate their thickening waistlines."
She admits to feeling slightly guilty whenever she looks at her wedding photos.
