This mostly-thrifted travel wardrobe is posted in honour of National Thrift Shop Day (August 17th), and is inspired by similar stories on The Vivienne Files.
Their sister-in-law is an artist and designer who works in natural and hand-dyed wools on beeswax-coated board. Recently she sent them a notecard with a photograph of one of her pieces, inspired by a summer on the St. Lawrence Estuary.

"Do we have any estuaries around here?"
"No."
"Could we go somewhere that's sort of like an estuary?"
"How about Owen Sound?"
"Oh, cool. We could go see the Tom Thomson Gallery, and do some hiking."
"I'm in."
What will she pack? She starts with this teal jersey dress.

No, it's not a silly idea. She knows lots of different ways to wear it.
By itself with a belt and a necklace

With a long cardigan and ankle boots (and tights, of course)

(There's another way you can wear the cardigan)

Under a vintage ultrasuede coat
Tucked into a black skirt
With a denim jacket
With a blanket scarf/shawl and black jeans (leggings would work too)
Under a teal pullover, with a scarf (and tights)
With a poncho and a grey beret
Well, she can't just live in the dress, especially if they are going hiking. She already has leggings and black jeans in the pile, so she adds a black square-necked top, that can go with either the skirt or the jeans, and a long-sleeved grey t-shirt. (If they were going to stay another day or two, she would put in a blue t-shirt as well.)
How about this tunic top? It's nice to have a different colour along.
That makes nine items of actual clothing, if you don't count ponchos and outerwear. Ten with an extra t-shirt. Nobody can accuse her of overpacking. Overdressing, maybe, but not overpacking.
She has a few other outfits in mind (besides the dress). The black top and skirt can go under her jean jacket
Or under the purple coat.
The black top and jeans can go with the long cardigan.
Or with the poncho.
And any of the t-shirts she brings can go with the jeans and her jean jacket, or under the teal pullover.
The tunic top can go with the jeans, or the leggings. Or it can get tucked into the skirt.
She is taking three pairs of shoes and boots: her new teal ankle boots, her thrifted Kate Spade snake print loafers, and her Allbirds Mizzles, bought last year, that are good for walking on trails.
Here are her coat and jean jacket. If she's smart, she'll remember to pack her warmer jacket as well.
The poncho and blanket scarf
A couple of other scarves, her beret, a purse, and a belt
She remembers to put in this other scarf (it's a bit warmer)
And some jewelry
Well, that's settled, then.
Thank you, Kathy!
