For Direct and Indirect Pronouns in Spanish
I've just finished my lesson about Direct and Indirect Pronouns, and I've learnt that to use this, (it goes like this)
ex.
Juan gives the cake to Maria.
Juan se lo da. (Juan gives it to her)
but what about with irregular verb(s), like GUSTAR?
How do I say "I like the red dress for you"?
THANKS!!

Gramatically, the parts of the sentence would be:
El vestido rojo (sujeto) me (complemento indirecto, a mí) gusta (verbo intransitivo) para ti (complemento circunstancial).
Of course you can say:
Me gusta el vestido rojo para ti.
Gramatically, each part of the sentence plays the same rol.
As qfred said, there is no direct object.
Furthermore, you could say:
Me gusta para ti.
The subject (el vestido rojo) is implicit in the sentence.
Gustar is not an irregular verb. That refers to stem changing verbs and verbs that have irregular forms (don't follow the typical pattern) when conjugating the different verb tenses.
It is an intransitive verb. (there is no direct object if you are trying to insert another object pronoun)
Your English sentence seems awkward to me. I would say it as "the red dress suits you" or "I like the red dress on you" [I like how the red dress looks on you"]. "for you, the red dress is an excellent choice", etc.
"me gusta el vestido rojo para tí"
