OBface. If Top Shop = fashion... ROFLMAO!!! I want to dress for my age. I think its unfashionable to be dressing in fashionable clothes that don't suit your age. Young does not = fashionable. You can shop at Top Shop and look frumpy.
The main problem with Top Shop is the clothes are designed for teenagers and early twenties. And whilst at 34, I can just about pass myself off as young enough for that, I don't want to as I'm not that age any more and it doesn't suit my behaviour. You do get treated according to the way you dress - I want to be treated as someone who is more mature than I was. I am fully aware that I probably have a choice that others don't have, but at some point I'm going to start looking ridiculous too. Thats as bad as frumpy imho.
Would I dream of shopping at M&S or Monsoon as an alternative? Nope, because they are awful. But I can easily see why women would - the 30 something market is a bit weird.
Early 30s represents a period in your life where you do start looking at different shops that you wouldn't have used when you were earlier. Its a weird limbo period. I've seen a number of threads from women in this age group feeling rather 'lost' and not really knowing where to shop anymore. There are other shops than M&S that cater for the age group, but I tend to find they can be rather prohibitive in pricing and can only afford them in the sales. And by all accounts there are lots of people who feel the same as me.
Having to shop in new places is especially true if your body shape has changed through having a baby. Shops like Top Shop have sizing that has narrower hip measurements that favour straighter figures than some other shops that are aimed at slightly older women which have more pear shaped sizing. In a lot of cases, women who previously did shop at places like Top Shop or Oasis couldn't even if they wanted to, as they no longer fit.
It creates something of a problem. You don't know quite how to do it, and perhaps don't have the luxury of time or money to try things and focus on yourself in the way you did when you were younger as your priorities are completely different. Putting yourself first or having the 'need' to dress to find a partner are less important.
Net result. Badly dressed frump. Or rather unsexy practical comfort.
