On "Friends", what did Joey buy Ursula for her birthday?

On Friends, Joey bought Ursula a cardigan for her birthday. The gift appears in the two-part first-season story “The One with Two Parts,” when Joey begins dating Phoebe’s identical twin sister.

Joey asks Phoebe to try the garment on so he can check whether it will fit Ursula. Phoebe briefly assumes the present is for her, since her birthday is the same day as Ursula’s, but Joey explains that it is intended for her sister. The awkward misunderstanding adds to Phoebe’s discomfort about Joey pursuing Ursula.

Ursula later gives the cardigan to Phoebe after deciding she is finished with Joey. Phoebe wears it while pretending to be Ursula at Central Perk, intending to let Joey down gently. Recaps and transcripts often call the garment a “sweater,” but a cardigan is a type of sweater, so the stored answer identifies the same on-screen gift. The episode aired in two parts in February 1995.
