I need something for a posh work do coinciding with my wedding anniversary next Friday night. What do you think of this black stretch lace dress ? Clearly gorgeous on a size 8 but what about a 12 weeks pregnant 18/20? Big boobs, large tummy at the best of times and a rapidly thickening waist. Figured covering the arms and showing a bit of cleavage would be plus points but am I being a bit optimistic?
