As you might expect from Taylor, this isn't aimed at mature women, so it's not a mature scent. It's a super sweet fruity-floral scent that is perfect for summer. It has notes of raspberry, green tea, peach and vanilla, and while it's not surprisingly a complex scent, I really love it! I think you'd like this if you're a fan of the seasonal Escada scents (Ocean Lounge etc) or Britney Spear's Fantasy.
It doesn't have the best staying power considering it's an Eau de Parfum, I'd expect the same kind of wear from a good Eau de Toilette. It's not awful, but only lingers on the skin for a few hours.
When I saw images of the bottle online prior to it's release, I thought it might be a little tacky, but in real life it's actually lovely. The purple bottle's got a holographic finish, and the charms dangling from the neck are inspired by Taylor's loves of birdcages, and the stars on her ceiling at home. For Taylor Swift fans (like me!) this is a sure fire hit. It's sold sensationally well in the US and I have no doubt it will do very well when it hits the UK in July.
