lenaregina, the flat rate priority boxes are free from the post office. The regular flat rate boxes (there are a couple of different shaped ones to choose from) cost $8.95 to ship and the new large flat rate boxes cost $12.95, regardless of the weight of the package. Delivery confirmation & insurance are additional if desired. I believe any of your items would probably fit in a regular box, but a long dress plus another item may need the larger size. For future reference, you can order priority boxes from USPS dot com for free, and they will deliver them to your house.
