Signing up to the Fast Fashion Fast has put a spotlight my spending habits, so I decided to note down any thoughts I had on clothing purchases. These are from the last few weeks.

Having signed up to the challenge, I immediately failed and purchased some hosiery. I was going out for a meal that evening and realised I had no flesh coloured tights, and the occasion and venue called for tights, so I had no choice but to make a last minute dash to Asda to pick up a pack of two for £4.00.

Later I looked at the Falke website, having heard that they are the best for good quality hosiery. I found what I was looking for, for £18.00. At first glance that sounded like an awful lot of money for tights, especially when you consider the £5.90 delivery charge. But if they really do last as long as they say they do maybe it's not so much. I could always search around for a stockist with cheaper postage. Would these tights last as long as 4.5 packs of my Asda tights? It's worth further consideration.

I went to Felixstowe to return an item and thought about popping in New Look, to have a look at their summer tops. Then I remembered signing up to Fast Fashion Fast and kept walking. I have plenty of summer tops anyway.

My summer slippers became uncomfortable. I purchased them last year from Asda and they've been worn a lot, but the soles had compacted and the bit between the toes had started to niggle, instead of buying another pair, I'm wearing my flip flops instead. Admittedly, and I totally see the irony here, these flip flops are a recent Primark purchase, 90p, chucked mindlessly into my basket as I made my way to the till point.

Then I fancied a gingham top to go with my new skirt. I looked on ebay and found one I really liked and won it, and I'll be able to wear it with a number of things already in my wardrobe. I've noticed that when I make an impulse purchase, like my green skirt, I invariably end up buying something else to wear it with.

This top was to wear with my green skirt, I didn't need it another skirt but I really, really, wanted it. I know I'll wear it a lot, and I feel that the more options I have the more I'll wear it, but how many options do I really need? I've always said there is absolutely nothing wrong with being seen in the same outfit over and over again.

I also wanted a plain black top to go with my green skirt - I thought about making one. So far I haven't acted on this. I do fancy making something but I really should do something about my mend pile instead, to make unwearable items wearable again.

I want a floaty summer maxi or midi dress - again I could make one but I don't really need it. I already have a maxi I like, why buy another?

The heatwave made me want some cooler PJs bottoms, I pondered something 3/4 length in a thin cotton fabric. In the end I found some pyjama shorts I forgotten all about. I don't like to sleep naked - what if there's a fire? or an intruder?

The hot weather also had me hankering after some non padded, non underwired bras. Nobody likes sweaty boobs. I looked into ethical underwear brands, and although I admit the search was hardly exhaustive (five minutes Googling), I came up with nothing. If you know of any, do let me know.

I wondered if underwear specialists M&S counted as fast fashion? I'd had it in my mind that, to make things easy, I wouldn't do any high street shopping at all during the Fast Fashion Fast, but not all high street shops fall under the umbrella of fast fashion.

Wouldn't it be great if there was a list... *Googles it* ... there is! On Wikipedia, it's not an exhaustive list I'm sure, but it helps. M&S isn't on it, but most of the shops I frequent on the high street are - H&M, Next, New Look.

It's clear that sometimes I shop for the sake of it, mindlessly. Sometimes I could avoid making a purchase by using something else from my wardrobe, but mostly it's made me really think about the high street and how to tell a fast fashion retailer from a non fast fashion retailer. Some are easy to spot - Primark, Peacocks, Matalan, but I was surprised to see Next listed as fast fashion for example.

Is the criteria absolute or are we to decide for ourselves? What high street shops do you consider not to be fast fashion? Are there any shops that you absolutely won't set foot in?
