Do set bonuses stack?

This is probably a stupid question, but do the set bonuses from items stack?

For example, if I only wore 3 items, that gave me a set bonus of +5 Dex, then wore 4 of those items, giving me a set bonus of +10 Dex, +10 Attack, will I get +15 Dex and +10 attack as a result? Or will I only get the set bonus of the highest set that Im wearing?

Thanks in advance
