Dress to Impress solves the weapons problem for the ball: only Royal Guards carry arms inside, so Jacob takes a guard's uniform for Abberline, who will smuggle the twins' gear into Buckingham Palace.
Part 2 of 4 in Sequence 9: Shall We Dance?
Find Abberline, whose disguise gives itself away through his eyebrows, voice and everything else. Climb St Martin-in-the-Fields to watch the Royal Guards patrolling a nearby building. Pick off one guard without killing him, take his uniform, and hide the unconscious man inside a carriage. Bring the uniform back.
Knock the guard out rather than killing him to keep the no-kills condition, and carry him to a parked carriage before the patrol sees the body.
Abberline finds the uniform still warm, agrees to meet Jacob on the roof of Buckingham Palace and rolls his eyes as Jacob leaves.
The guards you watch complain about missing the party, talk about cake and argue over whether Disraeli will show up. Abberline's line about the uniform being still warm is one of the memory's jokes.
The invitations from Double Trouble say swords must be left at the door, so the twins need another way to bring weapons in. Abberline doubts the threat at first, then points out that only the Royal Guard carries arms inside the palace.
Abberline agrees to take the twins' gear in disguise and arranges to meet Jacob on the palace roof, where you collect it in A Night to Remember.

A Night to Remember is the final main memory: the twins enter the Queen's ball at Buckingham Palace, Evie retrieves the vault plans from the White Drawing Room while Jacob rescues captive Royal Guards on the roofs, and both face Crawford Starrick in the vault below.
Double Trouble
Double Trouble begins the finale: after a bitter argument, the twins agree to one last job together, and Jacob has to steal William and Catherine Gladstone's invitations to the Queen's ball. The two split up, so you pickpocket each one in turn.
Family Politics
Family Politics has Evie earn the location of the second set of palace plans by driving Duleep Singh around London in a stolen royal carriage, so he can lobby three politicians about the kingdom Britain took from him.
A Case of Identity
A Case of Identity opens Sequence 6 with Jacob chasing a name in a letter: Plutus, Starrick's banker, and a meddler called Mr Dredge. You infiltrate the Royal Exchange to kidnap Dredge and find out what he knows.
