Simply traveling in the summer months, then having one or two pairs of shorts can be a great idea, especially when you need to keep cool or are heading to the beach.
1-2 Lightweight Sweaters/Cardigans
A merino wool weather or a light cardigan is a great idea when packing for 2 weeks in Europe. It can also be a good idea if you bring one that can be dressed up or down depending on the occasion.
1 Windbreaker/Rain Jacket
No matter the region or season, a rain jacket is always a good idea, as you can get caught out in a storm regardless of where and when you are traveling.
5-7 Underwear
How much underwear you bring really depends on at what point in your trip you want to do laundry. If you want to avoid washing at all, then go ahead and bring 14 or 15 pairs of underwear. They do take up valuable space, however.
5-10 Pairs of Socks
Like underwear, how many socks (and the kinds of socks) you bring really depends on your shoe preference and just how often you want to do laundry.
1-2 Swimsuits
Bringing a swimming suit is a great idea even if you’re not going to a seaside destination. You never know when you may go to a bathhouse, sauna or pool on your Europe trip no matter the season.
If you happen to be traveling to a beachy destination like Italy or Spain, consider bringing 2 pairs so you have time to dry each suit between wearings.
2 Bras
You may want to bring one regular bra and one sports bra, but this really depends on your needs and preferences.
2 Shoes and Flip-flops
Comfortable walking shoes (sneakers) I pair of dressier shoes or sandals. A pair of flip-flops/sandals for the beach.
