"So that" or "For ... to"

Does "so that" and "for ... to" have the same usage?

For example:

I bought this sweater so (that) you can wear it.

and:

I bought this sweater for you to wear it.

Is there any difference between the two expressions or do they have the same meaning?

Solution 1:

It seems to me in your example "so that" is a form of rationalization or persuasion. "You may wear it, but you don't have to."

"For ... to" is more of a command or a direct instruction such as "You will wear this sweater because I bought it for you."

Let's try a different example:

Jodi made coffee so that she would stay awake.

Jodi made coffee for herself to stay awake.

Here, The first example is a rationalization. "There are many ways to stay awake, but Jodi chose to make coffee.

The second example is a direct instruction. "The way for Jodi to stay awake is to drink coffee."

Semantics? The explanation above regarding emphasis makes sense.
