이 가방은 디자인은 예쁘다만 너무 비싸다. 

이 가방은 디자인은 예쁘지만 너무 비싸다.

Both sound okay but the last one sounds better. 다만 sounds old korean

Both are OK, However, usually elders say to 다만 to younger. That's the difference :)

When used in a sub-clause, 다 at the end most commonly functions as a quoting suffix. 
This usage is sometimes extended to clauses which contain independent and objective ideas rather than just concerning the case at hand.  People might also adopt such a style for effect or out of habit, as in your example.

Very often, phrases containing such 다 translates to a "that ..." noun clause in English. 

So, we might translated your sentences like these (with a slight exaggeration).
1. 이 가방은 디자인은 예쁘다만 너무 비싸다 => While it's true that it's got cute design, this bag's too expensive.
2. 이 가방은 디자인은 예쁘지만 너무 비싸다 => While its design is cute, this bag is too expensive.

Without 다 (#2), the clause sounds tightly connected to the main clause without any extra nuance, while with 다(#1), it sounds like a statement or thesis in its own right.  So #2 is a no nonsense, to-the-point way of saying it, and #1 is a somewhat unnecessarily broad sounding way of saying the same thing.

Note that in cases involving a real quote, 다 cannot be omitted.
For example,
1. 싫다는 사람을 왜 억지로 데려와?  Why bring someone forcefully who says they don't want to come?
2. 싫은 사람을 왜 억지로 데려와? (meaning is unclear) 

Here, 다 makes the word a quoted phrase. 싫은 사람 without 다 sounds like "someone you don't like", which is completely different from "someone who says they don't want to ..." in #1.
