These all look dreadful and are not really suitable for an interview. The tan thing should be burned, the double breasted looks what it is, second hand and old and one would not wear a sports jacket to an interview in most trades. Why not buy something decent for interviews rather than relying upon second hand clothes?
What do you sit on if you have never had a "suite" before?
Or go see a decent tailor for advice. You do not say what extent of change you would like - people have come here wanting to reduce by two or more sizes. A photograph of you wearing the thing would help as well.
