I buy clothing items all over the place and they're not usually the same brands. I love stores like Anthropologie where they have an assortment of everything.
If I had to choose a couple tried and true brands they'd be: YSL, Louis Vuitton, Frankie B jeans, JCrew, Frye shoes, American Apparel
BCBG, things from Buckle, Jcrew(for basics) and Hudson Jeans. For trendier pieces F21 b/c their quality sucks but if I'm only wear it for a season I don't care.
Dresses: Herve Leger, BCBG Max Azria, Sky
Jeans: Rock and Republic (love their designs), Seven For All Mankind (only the Crystal designs, regular ones are not my style)
T-Shirts: Bejewelled, Dom Rebel
Dress Tops/Sweaters: Miss Sixty, Wilfred (Aritzia's brand), Sky
Shoes: Christian Louboutin, Versace, Pedro Garcia
Jackets: MacKage (I Mackage)
Bags: LV, Chanel, Gucci
Jewellery: Tiffany's, CC Skye
I'm Canadian..so I'm not sure if some of these brands exists in the states (carried at Aritzia) I love Wilfred + Talula for shirts, American Apparel, Kimichi Blue, getting into Bannana Republic, J brand and COH for jeans.. I love Steve Madden, Tory Burch, Jeffery Campbell, Nine West for shoes.. bags I love COACH but dream of Chanel (a little out of my price range).
