Okay, here are the ones I know of, with my opinions.
Boutique-ish ~ for style
* Precious Vessels at Greenwoods Corner, Epsom ~ smart, casual, good range, combination of funky and classic
* The Carpenter's Daughter in Mt Albert Road, Epsom/Three Kings ~ funky ~ with seconds/sale shop across the road
* Extra Elegance further up Mt Albert Road heading towards the West ~ more for the older woman
* Platform Clothing in Dominion Road even further up, and just off, Mt Albert Road, another branch at Botany ~ good range of classic and funky
* TS in Newmarket and Milford ~ Australian brand, funky
* Kooky in various locations including Newmarket ~ more of a classic/corporate/special occasions range
* Magazine in Mt Eden Road (near Shackleton Road) and Takapuna ~ love it!!!
* Charismatique on East Coast Bays Road near Pupuke Golf Course ~ broad range of fairly classic/corporate styles
* Zebrano in Newmarket ~ good
* K&K in various locations ~ okay, good for basics
* City Chic in Newmarket and Manukau ~ for the younger woman! ~ mini skirts, jeans, casual, leather ...
Mass market ~ for basics
* Farmers ~ don't underestimate good old Farmers. Their basic range of Yourself and EllaJ are, erm basic, but good for wardrobe staples such as $30 black pants (who needs to pay a fortune for black pants?), but then there are more "designer" ranges such as Clarity, Table 8, Sirroco etc
* Ezibuy ~ Sara range, okay for basics
* Kmart ~ great for undies and swimsuits
* Postie ~ great for undies and lingerie and swimsuits
Um, I'm sure there are others but I cannot recall them.
Many of my real finds have come from TradeMe.
Also, when I have had loads of time I have trawled in the larger size section of SaveMart. It's the size of a rugby field and requires dedication and determination but can be a treasure trove. I once found a very styley black boiled wool 3/4 length coat by Jane Daniels for $29, a gorgeous vintage heavy oriental robe for $9 (it cost me $28 to add buttons and buttonholes but this is a stunning entertaining robe

, a $12 satin bias cut skirt which I wore to a ball ....
Any questions, Sarah, I'm yer girl. In fact, let's do a shopping or look-see trip sometime soon. I'd love to meet you.
