I'm going to a dance tonight. It's to celebrate a big occasion but the people and location aren't fancy.
I have two choices of dress. A silk bias cut maxi from monsoon which is definitely an evening dress, although on the more casual end of the scale. It has a bit of sparkle and thin spaghetti straps. Mainly black with a pink and silver pattern. It's much nicer than it sounds, is probably my most favourite dress I've ever owned. I don't get much opportunity to wear it but suspect it will be too much for tonight compared to what everyone else is wearing. I would dress it down a bit with flat sandals.
My other option is a cotton jersey maxi dress, again with flat sandals. Dark purple background colour with pink and lilac print. It's a nice dress, very flattering, wrap front with short sleeves, but it's a casual day dress, although nicer than my usual casual wear iyswim. I feel a bit dressed up when I wear it but other, more stylish, people would wear it round the shops.
Which one would you go for?
