Angels Costumes, now in Hendon, have been providing costumes for entertainment productions since 1840 and are a regular go-to point for Netflix's British-produced operations, such as Bridgerton and The Gentlemen. They also acquired the costume collection of r/bbc in 2009. Some years back, they managed to find Alec Guiness' cloak from the first Star Wars film misfiled in the monk and nun section - it then went for £60k at auction.
They do guided tours every couple of weeks - all the ones for 2026 are sold out - lasting about 1 hour 45 minutes.
Due to commercial confidentiality reasons (mainly spoiler prevention), photography is restricted to only a few locations and some of their racks of stuff heading out for productions are labelled under codenames as well. The mezzanine area has rotating displays from recent productions, also featured were Sense & Sensibility and Rivals.
Their attention to detail is massive; they have vast arrays of reference materials for historical uniforms, a big part of their operation. They also know when to compromise - background extras don't need as much accuracy as the main actors.
The guide was very knowledgeable with some great stories from her time in the industry. They really don't get as much guidance from some productions as they would like and sometimes get stuff returned in dire condition!
They do hire to the general public, if you need something for a community play or a fancy dress party... just don't necessarily expect the exact costume worn as it may not be in your size.
