Suits You, Sarah

Suits You, Sarah is an unmarked quest in Fallout: New Vegas, given to the Courier by Sarah Weintraub.

Quick walkthrough

 * 1) Talk to Sarah and bring her at least 30 vault jumpsuits.
 * 2) After that you will be able to have sex with her, be Well Rested and have a discounted stay.

Detailed walkthrough
After following the right dialogue tree, the player will be able to sell Vault jumpsuits to Sarah. She will accept jumpsuits from any of the in-game vaults, except for suits stolen from the guest rooms in Vault 21. With a Barter check of 65, she will accept Boomer jumpsuits and Boomer flightsuits. Vault 3 suits can also be bought at Mick & Ralph's, but they will only have 1-4 suits, and once you've purchased them they do not restock.

Vault 3 and Vault 11 both have large numbers of jumpsuits in dressers in their living quarters (24 & 28 respectively). See Vault jumpsuit (Fallout: New Vegas) for more locations.

You will receive caps, Strip reputation, and a discount on the Vault 21 guest room. After you bring her 30 Vault suits, on your next visit she'll mention missing the player character. You will then be able to have sex with her as you both "catch up" with one another, which gives the Well Rested bonus (which is normally not earned by sleeping in Vault 21's guest room). Also, after two Speech checks, 50 and 75 respectively, she will agree to having sex after receiving suits, along with accepting Boomer suits.

Bugs

 * Sarah won't accept the Vault 21 jumpsuit you are given at the beginning of the game.
 * Sarah will sometimes use a deeper female voice upon greeting you or after finishing a trade.
 * Sarah sometimes will take Vault 24 suits, but won't accept Vault 22 suits.
