I have been once before with a friend. We were quite casual in smart linen trousers and a top - as were most people there.
This year, DH's company are having a "corporate hospitality" day there and I have been invited too. Dress code is "smart-casual".
Initial thoughts were a maxi. However, if it rains I will end up looking like a Glastonbury wannabe rather than chic
Second idea was to go funky chic rather than lady-like: candy pink skinnies, pearl-grey Armani fitted jacket, grey loose-fit tank, floral scarf and ballet flats (you walk ALOT a the flower show so heels are definite no-no).
Thoughts & suggestions most welcome
