A big makeup bag is hard to find, if you're looking for something large enough to hold all your potions AND be equally stylish, but I think I've found it! This lovely poppy printed bag, £30 from Johnny Loves Rosie is perfect as it's big enough to fit bottles and has a useful section to keep my brushes snug.
I think the red and white print is very fresh and it would look great when toted around the first class lounge at Heathrow (I can dream OK?)
