They were aided by one woman's dress with a "kangaroo pouch" where they were able to conceal the bottles.
The theft happened last week as one woman distracted the clerk and the other two grabbed bottles and hid them in the dress pouch.
They didn't buy anything and got away with bottles valued at $1,125. They left in a blue Honda Odyssey with an Oregon license plate.
Anyone who spots them or has information is asked to contact Upland police.
The department says the city has seen a 20% increase in shoplifting cases over the past year.
