Ugh, all the people giving these kinds of lists: fluffy throw, slippers, PJ's, scarf, purse, phone case, lip gloss, make up, make up brushes, hair brush, hair dryer, hair straighteners, hair bands, face masks, costa/starbucks voucher, mug with hot chocolate sachets, pandora ring, watch, Amazon Echo, cinema voucher, books, perfume, lots!!
This is all such generic ‘female’ stuff. I’d have much preferred ‘my’ shampoo and a wall planner at 16 than this kind of stuff (I asked for and received the same shampoo for years as a teenager/ in my early twenties). Some people like practical gifts and don’t like clutter.
But specific present ideas aside, if her sister got more as number of presents - don’t worry about it, at 16 she’s plenty old enough to understand that her sister’s were cheaper gifts. If you spent more on her younger sister than (assuming you can afford it) give her some cash - my favourite present as a teenager - tell her you forgot to put it in her card, and tell her you wanted her to be able to buy herself something she loves.
Also give her the receipts for the clothes and let her change them (and yes, if she’s the kind who would enjoy it arrange to take her out for the day soon so she can spend her money)
