We cannot recommend using vacuum sealed bags because they are bad for clothes over long periods of time.  Clothes get their structure from air in their fibers.  When you remove the air from the bag, it is also removed from the fibers of the clothing and it can take a long time for those fibers to regain structure. The rule of thumb is: however long you keep clothing vacuum sealed, it will take that same amount of time for the clothes to regain their original shape.
