I would wear black socks with those clothes.

ropa elegante

ropa formal is formal clothes, formal wear, formal attire, etc.

ropa casual o informal is the opposite.

My guess is ropas bonitas. It's the literal translation

Answer 4

Since you included "tie", perhaps, "traje de negocios".

I'd wager a guess at "Un buen atuendo" but I'm not native, so it's just a guess.
