What gourd said about how many clothes and the abuse they receive is true. I have been pregnant/BFing/TTC on and off for over four years now and have gone up and down so much that I only have a handful of clothes in each size, and when you only have 5 tops that fit, they wear out fast. Also rushing around after toddlers/playing on floor/going to park every day is much more wearing on clothes (and on me
) than sitting in an office.
Saying that, I really believe in buying better quality stuff. I have Brora cashmere that is 5 years old and worn several times a week that looks absolutely perfect, and I refuse to deviate from it at all. I buy one cashmere thing a year and look after it religiously (hand wash in wool shampoo, delicate short spin in machine, over radiators to dry, never pegged out). I hand wash lot of my knitwear, even if it claims it can go in the machine, which I think helps it last. I do the same with the DCs' nicer jumpers. [bonkers]
T-shirts seem to wear out no matter how much you spend, so I tend towards H&M, although occasionally splash out if something is the perfect colour. I am loving the quality of these tops, they seem to wash really well so far (have only had them a month though).
Likewise trousers seem to wear out reasonably quickly, but a crap cut is so obvious that I think you have to spend some money on them.
Oh, and I try to stick to natural fibres as I am really sweaty in anything manmade, but viscose mix seems ok. I am a big believer in wool if you are at all sweaty. It is magic.
