This study seems to say women get it worse:
Acute alcohol consumption increases ratings of attractiveness to faces. This may help to explain increased frequencies of sexual encounters during periods of alcohol intoxication. At least in part, such increased attraction may be the result of alcohol consumption decreasing ability to detect bilateral asymmetry, presumably because of the reductions in the levels of visual function. We tested the hypotheses that acute alcohol consumption decreases ability to detect asymmetry in faces and reduces preference for symmetrical faces over asymmetrical faces. Twenty images of a pair of faces and then 20 images of a single face were displayed on a computer, one at a time. Participants were instructed to state which face of each of the face pairs displayed was most attractive and then whether the single face being displayed was symmetrical or not. Data were collected near campus bars at Roehampton University. Sixty-four self-selecting students who undertook the study were classified as either sober (control) or intoxicated with alcohol. For each face pair or single face displayed, participant response was recorded and details of the alcohol consumption of participants that day were also obtained. Sober participants had a greater preference for symmetrical faces and were better at detecting whether a face was symmetrical or otherwise, supporting the hypotheses. A further, unexpected finding was that males made fewer mistakes than did females when determining whether individual faces were asymmetrical. The reduced ability of inebriated people to perceive asymmetry may be an important mechanism underlying the higher ratings of facial attractiveness they give for members of the opposite sex and hence their increased frequency of mate choice.

This study says there is no difference between the sexes, however it looks like beer-goggles may persist for up to 24 hours for men:
Aim: A strongly held popular belief is that alcohol increases the perceived attractiveness of members of the opposite sex. Despite this, there are no experimental data that investigate this possibility. We therefore explored the relationship between acute alcohol consumption and ratings of attractiveness of facial stimuli. Methods: We investigated male and female participants (n = 84), using male and female facial stimuli, in order to investigate possible sex differences, and whether any effects of alcohol are selective for opposite-sex facial stimuli. We tested participants immediately following consumption of alcohol or placebo and one day later, in order to investigate whether any effects of alcohol persist beyond acute effects. Results: Attractiveness ratings were higher in the alcohol compared to the placebo group (F[1, 80] = 4.35, P = 0.040), but there was no evidence that this differed between males and females or was selective for opposite-sex faces. We did not observe marked effects of alcohol on self-reported measures of mood, suggesting that the effects on ratings of attractiveness were not due simply to global hedonic effects or reporting biases. Conclusions: Alcohol consumption increases ratings of attractiveness of facial stimuli, and this effect is not selective for opposite-sex faces. In addition, the effects of alcohol consumption on ratings of attractiveness persist for up to 24 h after consumption, but only in male participants when rating female (i.e. opposite-sex) faces.
