The lady, wearing a blue lace dress, hoiked up her skirts to show off her knickers to the crowd.
Her sheer underwear revealed every inch of flesh – and was so high cut it even showed passers-by a small tattoo of a strawberry on her buttocks.
Her hand on her hip, the woman laughed hysterically as she turned back to look at those behind her who had full view of her underwear.
Two friends with her gasped and laughed in shock at her display.
Although the woman flashing her bottom may have been the most revealing look seen at the racing, there has also been a host of terrible outfits over the last few days at the event.
Skimpy dresses fell foul of the windy weather, with many women nearly flashing more than intended.
Large hats, which are a must for the races, were almost whipped of women’s heads.
However, the ladies took it in good nature, giggling as they clutched onto their head wear.
Day three of Goodwood saw pouring rain, leaving riders to face difficult conditions on the course.
The ground was classified as soft, heavy in places and the non-runners have continued to come in as trainers protect some horses from very difficult ground.
The feature race, the Nassau Stakes at 3.35pm, lost three with Shutter Speed, Nezwaah and Wuheida all pulling out.
The favourite though remained as Ryan Moore rode Winter to victory, her fourth straight Group 1 win.
However, the poor conditions and tricky racing did not deter the women of Goodwood, with the trend for bright colours being the main theme of day three.
One woman wore an acid yellow, skintight dress that showed off every curve.
The skin-tight dress was topped off by an enormous fanned yellow hat, with a huge pink flower.
If this wasn’t enough the hat was covered in hundreds of pink feathers. Matching shoes with a hint of zebra print finished the eye-catching look.
