My dress sense tends towards the minimalist and stripped back, which works fine for work and casual, but seems much harder to do for weddings and posh parties. I went to a wedding last year in a plain blue dress from Cos, and felt distinctly under-dressed, but I also wouldn't have felt comfortable in the little jacket & floral frock look that most women of my age (50-something) seemed to be in. There's another wedding-like event coming up at the start of April, and I haven't got anything to wear. Any ideas about brands, or directions to go in, much appreciated!
