I've been invited to a friend's celebratory engagement lunch and I was told the dress code is smart/casual (this is absolutely no use to me, I really don't understand how to dress 'smart/casual'). The lunch is at a very nice restaurant in the city centre. I was thinking of wearing this dress: www.asos.com/ASOS/ASOS-Skater-Dress-With-Lace-Angel-Sleeves/Prod/pgeproduct.aspx?iid=2593859&r=2 (in blue), with nude pumps and an oversized nude clutch. Natural looking make-up and long, wavey hair. Any thoughts on the dress? What do you think to the arm detail? I'm 6ft, a size 12-14 and busty if that helps. Many thanks for all opinions!
