For me it varies. I tend to go through splurges and then buy nothing for 6 months. Already, 2 months into this year, I have spent about $2500 American dollars. I gained a lot of weight and needed practically everything. So I bought 4 winter coats in varying warmths, 1 trench coat, 3 pairs of jeans/jeggings, 2 black ponte pants, a couple of skirts, 4 or 5 blazers and a couple of ponte knit dresses. Two coats were expensive, for me. I will buy on sale if it fits into my plan...but I will also buy at full price if it is something that I really need and will work well for me. I would rather have fewer things. I was careful that many of my pieces can be altered and I can wear 3/4 of the year. Last year, I probably spent $500-$750.
I am now on SYC and won't get anything until April or May - I have no idea what my size will be then. I will buy cheap for the Spring/Summer and very few things. I tend to wear looser clothes in the Summer so I know that many of my tops will still fit. I just don' t need allot to get me through the Summer.
Disclosure : I also bought two pairs of boots and 2 pairs of shoes that I didn't not need...my feet have NOT gained weight. I was just on a "roll", unfortunately.
I am very blessed and lucky that I can afford this..otherwise I would have bought allot less. Our entire family clothing budget for the year, for 4 people with two growing kids, is usually $3000, so I normally work around what my kids need. If my kids end up spending more one year, then I spend less on my stuff. My husband RARELY buys clothes.
I should say that I am at SAHM and don't work or volunteer outside the home right now. So most of what I do is "domestic" stuff and school things for my kids. I think that my wardrobe is probably too big.
