Gossamer is something super fine and delicate — like a spider web or the material of a wedding veil.

The original gossamer, from which these meanings come from, is the fine, filmy substance spiders excrete to weave their webs. A dress can be gossamer-like, if its fabric is so sheer as to be see-through, or almost. Your chances of going to a good college are "gossamer thin" if you've never cracked a book in high school.
