Women spend only 40 minutes getting ready to go out with their man, but a staggering one hour and three minutes getting dolled up for their pals, the study of 2,000 women found.
Nearly two thirds of women admitted they set out to wow their friends with their 'look' and said they always compare their appearance to their mates, 'The Telegraph' reported.
However, women are more likely to opt for a casual look when on a date with their man, but choose glamorous outfits when going out with the girls.
Researchers found 44 per cent of girls actually prefer the process of getting ready for a girly night out as much as the night out itself.

"There is something really fun about getting ready for a girls night out. The preparation almost becomes part of the night itself, and creates that bonding moment for the rest of the evening," a spokeswoman for Malibu Rum said.
When getting ready to go out with friends, almost half listed a cocktail mixing session as the most enjoyable part of the evening.
A third said they love sharing beauty tips and swapping make-up and forty per cent religiously blare out the tunes for their friends to sing and dance to.
But when getting ready for a night out with their man, nearly 50 per cent said they rush as they are aware that their partner gets ready in two minutes.
They spend a further one hour and 41 minutes organising the evening via text messages, phones and email conversations.
Another hour and 16 minutes are spent undergoing treatments such as a new hair-do, tanning and a manicure.
