Me too! I'm going on some version of SYC in January too! But I'm nervous because I don't know exactly how I'll react to it. I haven't decided how strict I am going to be about it--I need a plan. Maybe I will do a SYB or one item per month or something. I would like to get a pair of lounge pants to replace my ancient black sweat pants. And still looking for a replacement rust short sleeve mock neck sweater. And I've thought about getting a navy or black blazer to wear with jeans etc. a la Parisian chic, but that takes time to find the right one. And I don't have any stylish casual shoes. Etc. etc. And like you I am on the hunt for a red cardigan (bought two from Nordstrom, the Only Mine and the Laura Hansen, but they didn't look great on me so I returned them).
Guilty confession--I have been doing a lot of shopping this week to beat the Dec deadline. Granted, they are to fill more basic/boring casual wardrobe needs (T shirts from H&M, white skinny cords from Anthro, rust colored cardigan from J Crew), but still...I thought I was done with my closet!
I also just found out I won a copy of the Little Guide to Vintage Shopping (woohoo!), so maybe I will explore consignment/thrift stores. The few times I have tried I haven't been successful so hopefully this book will be useful to teach me how to shop used. And I have a collection of Paul Frank purses that have just been languishing, so maybe it will motivate me to learn to sell on eBay so I can use the proceeds for new clothes.
I love your list that you made of the items you plan to buy next year and your budget. So organized! I may have to copy that. Good luck on your SYC! I will look forward to wardrobe remixing along with you!
