Find a cheap dress with a potential.
Buy some fabrics and tulle that are (in some sense) opposite color.
Cut the dress into pieces and keep the useful ones.
Make a new top and attach it to sleeves. I sewed it by hand.
Make the skirt part a bit shorter from the top and crimp it to match the new (orange) top.
Put everything together, take a picture and think about it. Now this looks a bit oldfashioned, don't you think?
Make a lace from leftovers.
Cut the back side of the top.
Add some lace to the top like you mean it.
Crimp the tulle.
Attach the tulle to the skirt so that it shows just a bit.
Add a belt if needed...
... and some butterflies...
... and some velvet roses too.
