I have a work event coming up which requires I wear a work provided white shirt with plain black trousers. The shirt will not be provided until the day of the event and I'm convinced it's going to be a poor fit. (European sizes which have been estimated on our behalf with no samples. I have been ordered a 10 but I usually have an 8, I despair!) I usually go for a skinny fit trouser, in grey or a slight pattern so having to buy plain black especially but I'm not sure if a poor fitting shirt will work with this style. I'm thinking maybe a higher waisted wider trouser so shirt can be tucked in to avoid looking like a poorly dressed school girl or waitress. Any ideas where I could find such a thing? Or something which might work better?
