I usually buy clothes which are too big for me. I just live in fear that I'll buy something and it'll be too small. I kept asking to try prom dresses on in a size twelve/fourteen, and then the women told me I was actually supposed to be wearing a size eight. I bought leggings in size twelve when I am a size ten in them. I always go by the rule 'it's better being too big, than too small.' but in reality, wearing something too big can completely drain your figure. It's not entirely our fault though, there's nothing worse than trying an item of clothing, which you really like in a shop, and finding that the smaller size is way too small and the size up is way too big.
