Hello, I am attending a wedding in a few weeks and am trying to figure out what to wear. I keep hearing about chiffon dresses, but I have no idea what type of clothes chiffon actually is. I want to make sure I choose an appropriate outfit for the occasion, so can someone please explain to me what type of clothes chiffon is? Is it a formal material or more casual? And any tips on where to find chiffon dresses would be greatly appreciated! Thank you.
