LONDON (REUTERS) The scariest nightmare for this London costume shop would be to run out of outfits at their busiest- and most profitable- time of the year.
Halloween is big in the US - it was brought there during the 19th century by Irish and English immigrants.
Research group Mintel Market predicts that Brits will spend £320,000,000 on Halloween in 2017, up 3.2 per cent form 2016.
Some think this might have to do with people's desire to forget about current world issues.
Says Andreou: "We always see a trend in things like zombie movies, vampire movie, horror movies when things are bad because it's a pure escapism. And I think with regards to Halloween people dressing up, that's something to do with it, because I have never, like I say every year it gets so much more popular and people go more and more gruesome."
Andreou said among the most popular outfits are witches- sexy witches in particular- but also scary movie characters such Pennywise, the clown from It, and characters from the Netflix series Stranger Things.
Some however decide to go a bit more exotic.
Model Felicity Hayward says: "People only dress up on special occasions like Christmas and I think Halloween's just the one when you can just do what you want."
Angels expects to receive 200,000 visitors with queues of up to an hour long.
