I'll give her points for trying and looking like she put in an effort, which she obviously did!
Yet she didn't really get it right, the dress looks too much like an evening bridesmaids dress or a glamorous mother of the bride. The material is too thick and way too shiny for a day look. While she is following the dress code of not having dress straps less than an inch, not many women who are in the royal enclosure wear strappy dresses and show their shoulders. Why on earth couldn't she just have a looked at what some of the royal women wore last year or wore in the last 2 days like Kate, Zara, Beatrice, Eugenie etc. I guess Zimmerman, Suzannah London and Emilia Wickstead weren't handing out freebies.
I actually like the mini kelly as a fancy day bag, unfortunately the colour doesn't work with the outfit. Craie in epsom leather looks a bit too cream/blush. She would have been much better with the new colour, gris pale with gold hardware. This has cooler undertones that would go with blue and the white gloves.
The hat is also too shiny and matchy matchy to the dress, even if she wanted the same colour she should have had a different texture to the shiny dress.
