A few years ago, my sister showed me a leather look biker jacket that she'd bought for my niece (who was then 14). I tried it on, and it looked so good that the sister insisted I take it. (Sorry Jen!)
A few weeks ago, I was housesitting for the sister, and left behind a shopping bag with a new jersey dress that I'd just bought. Sister tried it on, liked it. Asked her daughter if she liked it too and got a resounding yes.
