I can't find much usage of "opt for" in my dictionary. The one that shows is very vague and get me confused. Does "opt for" roughly mean "prefer". When "opt for" is used,should it be in a comparison sense?
Can I say "I opted for casual wear" ? Or should it be "I opted for casual wear over formal wear"?
And when you use "prefer",should use put two things in a comparison sense?
It means choose. I opted for formal wear = I decided it was better than casual.
