Crisp cotton shirts are the epitome of formal work wear - they go well with trousers and skirts. But the one thing I dread is the peeping gap between the buttons! It was especially a problem with shirts that weren't tailored to my measure and only fit me just decently. I would try to find some temporary solutions for it - I would carry safety pins with me and the button line of my shirts were lined with safety pins or fashion tape. They would work but also ruin my shirts!
