There is a little bit of everything packed into this store, from basics like tanks and jeans, to work separates like blazers, skirts and dress shirts, to gorgeous wool-cashmere coats and silk dresses. Almost everything they carry comes in petite-friendly XXS and 00, and jeans as small as 23.

There are several locations, including Pacific Centre Mall, Robson Street, Oakridge Mall, Metrotown Mall, Richmond Centre Mall, and Park Royal Mall.


Holt Renfrew

This is the place to go for high end designer labels. As any high end designer label goes, you can get stuff in super small sizes. Sadly, the only times I can afford to shop here are when they have their seasonal clearance sales.

It's located downtown at Pacific Centre Mall.


H&M

All petites already know H&M! Locations include downtown at Pacific Centre Mall, Metrotown Mall, and Park Royal Mall.


Banana Republic

On Robson Street there is a huge BR with a large petites section. Other locations are Metrotown Mall, Oakridge Mall, Pacific Centre Mall, Richmond Centre Mall, and Park Royal Mall.


Le Chateau

Sizes as small as XXS... I think I've even seen XXXS on occasion. Numerical sizes go as low as 00. There's an outlet on Granville Street, and store locations include Robson and Burrard, Pacific Centre, Metrotown Mall, Richmond Centre, Park Royal, and more.


The Bay

Now carries brands like Theory, Halston Heritage, Free People, BCBG, J Brand, Diesel, Seven, and tons more etc. Several brands have petite lines, such as Ralph Lauren. The lingerie section is enormous, and you'll find lots of options for petites. Stick to the downtown flagship location. It has multiple floors of clothes and accessories. The other Bay stores are dismal in comparison.

The downtown location also has a new Topshop store with a petite section! http://www.thebay.com/eng/brands/search/womens-thebay/18833?ad=test&gclid=CIb2gKem4rUCFQlyQgodkVMAog


RW&Co.

Sizes as small as 00, their clothing is very work appropriate. Locations include Robson Street, Pacific Centre, Richmond Centre, and Park Royal.


Plenty
http://getplenty.com/

Jeans and casual pants as small as 23. I'm not sure about tops, but I know a tiny girl who used to work there and buy all her clothes there. Locations include Robson Street, Metrotown, and Richmond Centre.

I just went to Plenty last week. They have a few brands with tops in XXS, and they fit pretty well on me. Very exciting. They also had the tiniest miniskirts I have ever seen, I felt like I could put one leg in them.

Also: F21 - one location in Metrotown only. Does anyone know when their Robson street location opens?

Oh yeah, good call on F21! I don't think their Robson location will be open for a long time. I went by there a couple weeks ago and it's still an open construction site covered in mesh netting, no actual walls yet.

I just discovered this designer while I was at the One of a Kind show this weekend: Angela Chen

Sold at this store on West 41st:

I met Angela, and she is around my height but much slimmer. Her skirts and pants in size XS were a bit too small in the waist for me. The skirts were a great length.

Lululemon lab (http://lululemonlab.com/details/) makes more streetwear than a usual lululemon store, and their size 2 is tiny. Cambie & Broadway, kitty corner from the Broadway/City Hall skytrain station. Their facebook site has updates with their latest items.

I just saw this store in the Pacific centre called Ever New. I guess it's an Australian company, which is interesting.

I didn't try anything on, but their smallest size looked TINY.

F21's Robson Street store is open, I've already made good use of it. Ever New has some pretty dresses!
