Just ask the recruiter outright the expected style. They want you to be hired so will happily give you everything they can for you to be successful! Generally tidy dressing, no matter what you wear, and grooming will give a good impression. Dress expectations is a good marker for you too; if they expect full suit, and all your interviewers wear ties, what read does that give you on their culture? Finally; overdressing can only ever give an impression of eagerness (vs underdressing which can set you back) so err on the side of caution. Ultimately, any good company should care more about your skills than your clothes....
