- Scarf from Spain for Aunt Alma
- Tie from Italy for hubby
- Silk blouse from France for me
- Postcards from everywhere
- Jeans to replace John's that he tore while hanging out with new friends in the teen lounge.

You'll still need to study clothing sizes in other countries as well as currencies (Euro in the three countries I've mentioned), but here's a bit of a "cheat-cheat" to help you with the names of various pieces of clothing.
