I'll be attending a wedding in July. I usually would wear a dress, but this time I'm thinking black midi circle skirt and crisp white shirt/blouse. I'll be wearing black Dr martens (either shoes or boots, haven't decided yet), maybe black fishnet tights, and probably a smart black fitted Jaeger blazer. I'll also probably wear a sparkly coloured brooch either on the jacket lapel or at the throat of the shirt. I'm 5'5" and size 12ish. Hoping to keep under €100 total. Important not to end up looking like a waitress!!!!! Any suggestions?
