And the formal event? It was my cousin's wedding. This dress lasted me the whole wedding and the whole evening and it was still comfortable to wear!
The dress was made out of light blue charmeuse. It is asymetrical and full length. It was also made with Simplicity 2692.
Here are some close-ups of the bodice. The bodice is gathered in the front and is connected to an ungathered "midsection", which is also connected to the gathered skirt. For the wedding ceremony, since it was in church, I wore a shawl since the dress had no sleeves. It worked out pretty well!
