Christmas Present For Girlfriend?

So christmas is coming soon and im not sure what to get my girlfriend. I has thinking of buying a stocking and puting her name on it and then buying her favourite candy which is skittles, so i was going to buy her a bag of every flavour and there is this necklace that her bestfriend told me that she might want because she has the matching bracelet and then the last part would be like pants from lululemon because i think she likes them but she finds them expensive n i know she atleast likes the headbands from there... so what do you think lulu, necklace, skittles :) haha n a stocking. does this sound good? thanks so much :) we are 18 n 19
