I need help. I'm looking for gift ideas for my sister in the States, who is very much an Anglophile expecting me to bring back something amazing. I want to gift her something very quintessentially British, possibly a cult "find" AND a fab beauty product that works. I myself am usually an ogre in daily life and know nothing of this subject beyond Olay face cream at Boots. She's a lady of discerning tastes, unlike me. Any ideas?
