I pack a similar capsule wardrobe for each trip. I don’t go on cruises so everything I take is very casual. To me it depends on exactly when in summer you are going and what the weather is a few days out. I’d have options in case it’s unseasonably hot or cold.
4-5 SS tops - I use the cotton/modal blend from Lands End because I know they will dry overnight
1-2 LE cardigans. I have been doing black and cobalt. I have the tees in matching colors so it’s more twin set looking if I need something slightly dressy altho I’ll always have my athletic shoes on
1 LS dri-fit quarter or half zip top. This is a new addition this trip and I have worn it at least part of every day for the last 5 weeks of travel. I’ve been in England and Scotland and it’s been chilly the last few weeks with high temps in the low 60’s.
1-2 crop pants - If temps are hot then 2 pr. I got some poly ones on sale at Penny’s before I left this time and they did well. Dried overnight. They are kind of the same fabric as many travel pants are made of.
2 pr long pants - wear one on the plane. If the forecast looks to be chilly, 1 of these is a pr of cotton/poly blend jeans that I know dries overnight
3 scarves (no jewelry- I realized I just didn’t wear it as much as the scarves and even a bracelet or 2 adds weight)
2 pr Altra athletic shoes
Underwear, pjs, socks
Waterproof rain jacker
All colors of tees go with all pants and all cardies. Scarves go with everything too. The combo of each shirt with each pr of bottoms gives me 15 outfits (with 5 shirts and 3 bottoms). Adding each scarf to each is 45 more possible combos.
I travel using Rick’s 21inch rollaboard. I have a small day pack for my personal item. I pack my travel purse and wear a travel wallet cross body on the plane with my money belt.
Decant your shampoo and conditioner in to smaller containers. I have been checking my suitcase but I still get all my liquids into the 3-1-1 sized ziplock.
Have a terrific time!
