They also carry the Straw Hats' Jolly Roger to symbolize their alignment.
The crew is led by Cavendish, and is composed of 74 members who followed him after he was exiled from his homeland, the Bourgeois Kingdom. It also includes his pet horse Farul and Suleiman, who joined after the Dressrosa Arc. The crew members wear the same type of hairstyle, with a big bun, and curlers on the sideburns. All of them are part of the Straw Hat Grand Fleet.

Little is known about the crew's strength but its captain, Cavendish, has a bounty of 330,000,000. Cavendish gained fame as a "Super Rookie" of his generation one year prior to the emergence of the "Worst Generation".  It should also be noted that the crew was strong enough to survive the New World without joining sides with an Emperor.
The Beautiful Pirates' ship is called Sleeping White Horse of the Forest.
In the past, Cavendish was the prince of the Bourgeois Kingdom, but he was exiled for his popularity among young ladies, who wouldn't marry. He indeed left the country with "only" 500,000,000 in tow and 74 followers, who would become the Beautiful Pirates.
At some point in the past, the Beautiful Pirates visited the Rommel Kingdom, where it was plagued by the crimes perpetrated by Hakuba, Cavendish's second personality.
One year before the beginning of the main storyline, Cavendish and his crew entered the New World, where he made a name for himself. A year later, however, he became overshadowed by the rookies of the "Worst Generation". He resented them heavily for this and sought to take his revenge by killing them all.
Cavendish entered the Corrida Colosseum in order to compete for the Mera Mera no Mi. He lost in the fourth block of round one of the tournament, and afterwards was turned into a toy by Sugar. When he was freed from the curse by Usopp, he let go of his grudge against Luffy and joined him in the decisive battle against the Donquixote Pirates.
In the aftermath of the battle, Suleiman joined Cavendish's crew. Every one of the wanted warriors who sided with the Straw Hats gained 50,000,000 added to their bounties, including Cavendish.
The crew was later one of the seven groups to request permission to become subordinates of the Straw Hat Pirates. When Luffy declined the offer, Cavendish along with the other representatives pledged themselves to Luffy anyway, becoming part of the Straw Hat Grand Fleet.
The Stories of the Self-Proclaimed Straw Hat Grand Fleet
As the Beautiful Pirates were sailing, Cavendish reminisced and told Suleiman about his past.
