I always buy the same brands but generally only one piece a month or even each 2 months, so there isn't exactly a designer I buy regularly since I rotate. When it's been half a year orso I bought something Chanel I feel like I need an update

, same with Balenciaga. I've already had a love affair with those 2 for about 4 years I think.
Clothes in general: Balenciaga, Balmain, Chanel and less frequently (which is like once a year orso) Dolce, Versace and Chloé.
Very fitted and simple clothes: Dolce and Versace (I got a great cashmere/silk Versace jacket).
Special clothes (things with crystals, paillettes, nice detailings, embellishments, drapage,...): Chanel, Balmain, Balenciaga and Chloé.
Body's: I wear them a lot under my high waisted skirts. I got one from Wolford in cotton and one from Alaia which has a shine. I love the Alaia one, but I tend to wear it less than the Wolford one since it was bloody expensive and I want to be careful with it and not sweat in it,...
Tights: Wolford and Falke for simple ones and La Perla for a nice design on them orso.
Pumps and boots: a lot of different brands: I have: Chloé, Sergio Rossi, Balmain, Lanvin, Versace, Casadei and some unknown brands too.
Sandals: I love Balenciaga sandals (though it does depend on the collection as I hate those from summer 2009).
Snow boots: Mukluks: they're comfy yet beautiful which is a (for me) very difficult combination to find. I hate that I don't find those any longer at stores.
Ballerina's: I love Chanels ballerina's (in particulary lace and satin ones).
Swimwear: La Perla and Missoni (though lately more La Perla).
Underwear: La Perla, Roberto Cavalli, Dolce&Gabbana.
Bags: mostly Chanel and Balenciaga but I also have a Chloé paddington (which I still like a lot, for me it wasn't an it bag), a Gucci Indy and some others.
Jeans: I have lots of brands (Rock&Republic, Dolce, Balmain, Miss Sixty, Victoria Beckham,...)
Make up: usually Guerlain lately (but Armani foundation).
Hair care: Kérastase.
