If you really, really liked something...but it was Rihanna for River Island..what would you say was the cut off age to wear it? (not anything revealing/ overly trendy 'young' looking as such - ) I wear a lot of River Island. I love a jacket and a maxi dress from Rihanna's range. I don't normally go by age for most stuff. But I feel..I'm too old for designed by Rihanna (and a friend told me, too old for River Island!) I know I'm too old whispers 42
