Which is structurally correct?

The only correct thing here is the structure but this is one lousy 'she is so ugly' attempt that will not serve its purpose.

Better try something in line with the following.

She's so ugly Dracula don't want her.

She's so ugly, she tried to enter a Hallowe'en contest, and the judges said: "Sorry, no professionals."

Yo mama's so ugly, her shadow quit

hi,

both are correct and there is still a third way to say it : she was a too ugly girl to get asked out by him

No, that one doesn't work.

too adjective a noun -- okay

too a adjective noun -- not okay

I think the first one is better, though. The second one is almost redundant, because of courses, she is ugly as a girl. We already know she's a girl...

But you don't in similar constructions.

The shelf was too high for me to reach.

It was too high a shelf for me to reach.

NOT: It was a too high shelf for me to reach.

The price was too high to pay.

It was too high a price to pay.

NOT: It was a too high price to pay.
