Aritzia fleece. from the founding story to the fits I would reach for first.

Aritzia Fleece: The Vancouver Hoodie Story, From Perfect to Mega
Where the hoodie starts
In 1984 a 23-year-old named Brian Hill opened the first standalone Aritzia in Oakridge Centre, a mall in his hometown of Vancouver. The family had already been selling something under that name inside their 70-year-old department store, so this was a family idea given its own address. Hill also picked the name partly because it began with an A and would sit at the top of listings. That is a very fleece-adjacent kind of planning: small, practical, a little sly.
I think the Aritzia fleece obsession makes sense once you know the brand has always been about its own labels and its own fits. Tna, the label behind a lot of the comfort pieces, was launched to deliver premium comfort, and the Sweatfleece line is where that idea got serious. The fabric is a midweight cotton fleece with a soft-brushed back and a sueded face, and the real trick is the number of cuts: Perfect, Boyfriend, Mega, Boxy, raglan, cinch. You pick a shape, not just a color.
For October, the hoodies are where I would begin. The Cozy Sweatfleece Perfect Hoodie in Cacao Nib Brown is the classic: kanga pocket, dropped shoulders, ribbed trim, and a brown that works with denim, black leggings and a camel coat. The Mega Raglan Hoodie in Laurel Olive is the roomier option, so I would pair it with straight jeans and clean white sneakers. The Mega Hoodie in Gala Plum is the one I would wear with a skirt and boots, since the plum looks richer against dark tights.
If you want a graphic, the burgundy hoodie with the varsity lettering and the gray Mega Raglan with the red EST. 1984 print both nod to the founding year. Test the hood: pull it up and make sure it sits without swallowing your face, then check how far the hem lands against your waistband.

Crewnecks and zip-ups for layering
Forbes notes that nearly every Aritzia dressing room has no mirror, which sends shoppers out into a shared space to check the fit. That is the right setting for a zip-up: open it over a tee and you can see how the fleece layers instead of bunching. The shapes are the story here, so I would decide on the cut before the color.
The Cozy Sweatfleece Perfect Zip Hoodie in black is my everyday pick: kanga pocket, double-layer hood, and it goes over a slip dress or a button-down. The Mega Zip Hoodie in Geode Purple is oversized with inseam pockets and a bubble-silhouette hem, so it wants slim bottoms like leggings or straight dark denim. For something sleeker, the Mega Cinch Zip-Up in Heather Chrome has a drawcord waist you can pull in, which makes a good balance with wide trousers.
On the crew side, the Cozy Sweatfleece Perfect Crew in Geode Purple is the lilac one with classic ribbed collar and cuffs, and the Boyfriend Boxy Sweatshirt in Admiral Navy has ribbed side panels that give it a squared shape. The Boyfriend 1/2 Zip in Plein Air is a pale blue mockneck that works on a cold morning commute.
Fitting-room test: raise both arms. A good fleece top should move up an inch, not ride to your ribs, and the cuffs should stay put. What I would skip: the Mega cuts if you plan to wear a thick coat over them, because the extra volume gets crowded under a wool shoulder.

Sweatpants with real shape
Good Housekeeping describes the range of silhouettes as incomparable, running from Perfect and Boxy to Boyfriend and Mega, plus cargo and barrel-leg options. That is exactly what you see in the sweatpants, and it is why I treat them like trousers rather than loungewear.
The Mega Straight Sweatpant in Magnolia is a pale pink with a roomy leg and inseam pockets, so I would wear it with a tonal hoodie and white sneakers. The Boyfriend Wide Sweatpant in Laurel Olive has a mid rise and a triple-stitched waistband, which keeps the line neat under a cropped jacket. The Mega Cargo Sweatpant in Magnolia adds large pockets for a more street-ready outfit. The Mega Jogger in Rich Mocha Brown has a rollable waistband and suits anyone who wants a high rise with a gathered ankle.
The Boyfriend Barrel Sweatpant in Heather Chrome is the shape I would reach for when I want the silhouette to curve, and the Mega Flutter in the same gray kicks out over a boot or a platform sneaker.
Test the length with the shoes you actually plan to wear: a straight or wide leg should graze the top of the sneaker, not pool on the floor. What I would skip: the balloon jogger in Cacao Nib Brown if you prefer a clean, narrow ankle, since the gathered hem is the whole point of it.

Polartec and Bigfoot fleece layers
Cotton fleece is a brushed fabric used for warmth, and it has a different feel from French terry, which has looped interior. The pieces here are another family altogether: shaggy Polartec Thermal Pro and the low-pile Bigfoot Fleece microfleece. This is where I would look as the temperature drops.
The Polartec Thermal Pro Highlands 1/2 Zip in light gray is a shaggy mockneck with zippered pockets, and it looks good over a base layer with leggings. The Twilight Zip-Up in Cacao Nib Brown and Black is a relaxed shape that I would put under a long coat for a weekend walk. The Exploration Zip Hoodie and the Canyon Hoodie, both in Villa Blue, are the pale blue options, and the color reads fresh with gray denim or black ski pants.
Among the Bigfoot pieces, the Outlook Zip Mockneck has a cinchable shockcord hem, the Mellow 1/2 Zip in Americano Brown has dropped shoulders, and the Terrain 1/2 Zip in Dew Blue is a pale oversized half-zip. They are smoother and less bulky than the shaggy ones.
Fitting test: zip to the top and turn your head. A mockneck should sit without pressing on the jaw. What I would skip: the shaggy pieces under a fitted blazer, since the texture adds bulk to the sleeves.

Sweatfleece shorts and capris, styled for October
Shorts in October only look odd if you style them like July. With tights, knee boots and an oversized hoodie they become an actual cold-weather outfit, and the capri is the surprise piece of the group.
The Cozy Sweatfleece Mega Above-Knee Short in Heather Chrome has inseam pockets and an infinity loop drawcord, and it sits longer than the others, which is useful with tall boots. Perfect Hi-Rise Mini Short in Cacao Nib Brown has an elastic waistband and is the simplest to build around. The Mega Hi-Rise Mini Short in Heather Cloud White is the lightest in feel, and the Boyfriend Lo-Rise Mini Short in Gala Plum is the one for a low-slung, early-2000s look. Another is the Micro Short in Burgundy and Light Birch has side slits and the ARITZIA graphic, and the pink Micro Short is the sweetest of the group. For something different, the Mega Flutter Micro Short in No-Stress Beach Blue has a wide flutter leg.
The Cozy Sweatfleece Perfect Capri in Gala Plum is a super low-rise slim fit with an infinity loop drawcord, so I would pair it with a cropped zip-up and a pair of flat boots.
Check the waistband sits where you intend, since low and high rises change the whole look. What I would skip: the micro shorts as a lone layer on a cold day, since they need tights.

How I would choose from here
I would begin with the shape, not the color. Pick the fit that suits your frame, a hoodie in Perfect or Mega, then choose the brown, olive or plum that works with what you already own.
After that, add one bottom that makes you want to leave the house, the wide sweatpant or the barrel leg, and one shaggy layer for the coldest week.
Hill started with a department store corner and a name that sorted to the top of the page. A hoodie that makes you feel put together on a Sunday errand run is a decent descendant. If you want to keep browsing, I also put together The North Face Coat for Women and Fleece Jacket.
