Can you link to some of the dresses you wear to wor? Not to give us party wear inspo, but an idea of what shape/length/neck/sleeve you feel comfortable in.
What shoes do you wear to work?
Are you opposed to any sort of sparkle?
I do have an idea what you mean - I've been hunting for 'something nice to wear' to a couple of dos and honestly, despite having a few hours to myself, a reasonable budget and a figure that should be easy to dress, I really struggled.
Too many sequins, too much...I don't know..just too much going on - length, sleeve, frills and what have you.
I ended up with a simple black polyester velvet jumpsuit from Tu for £25.
