I currently an 8-10 (uk size) and I think my ideal size might be a 6 (I'm only 5'1 but have a medium frame). But I worry that by losing weight to look good in clothes, I might actually hamper my wardrobe because the lower sizes are less common in high street stores. Nearly all stores have 8s, the young fashionable stores usually have 6s( although there's usually less of that size in stock) and I have never, ever, seen a uk size 4 in a high street shop. I know things are different in America. Because people talk about size 0 as if it's quite a common size for clothes. But in the uk, apart from on models, a size 4 is unheard of.
