At my school, nearly all the Emmas were really attractive, at least a 7+, including a couple of absolute stunners. Small sample size though obv.
As mentioned previously, Holly and Heidi are nice names, but that may be clouded by the I've only known of each, and both were ridiculously beautiful.
Despite the goddess that is Megan Fox, I really dislike the name Megan. The 'egg' sound is too harsh and reminds me of the word 'Smegma', which is not good for obvious reasons. Pronouncing it 'Mee-gan' is no better.
And to whoever really liked the name Justine, I presume you are not from England. Over here this name genrally belongs to the Trisha-trash dregs of society who are great-grandmothers before they reach 50. (Apologies to any one with a Justine in the family
)
