Am a freelancer/work from home, almost never have to wear professional dress and haven't for about five years... but now need to present at big event and have no idea what to wear. Am petite (5ft 2in), size 8, brunette, fair skinned. Wondering about a dress with long black boots/cardi? I like red/deep blue/teal/emerald type colours and they suit me. Any or all advice welcome, I feel like a teenager starting a first job
