LORELAI: And then there’s the full on Diana [veil].

Lorelai is referring to Diana, Princess of Wales, born Diana Spencer (1961-1997). Diana married Charles, the Prince of Wales and heir apparent to the British throne, in 1981. At their wedding in St. Paul’s Cathedral, she wore an ivory silk and lace vintage-style wedding dress with a 25 foot long train; her tulle veil was likewise very long, and floated behind her as she walked.
Diana and Charles divorced in 1996 – another famously disastrous marriage to give a hint to Lorelai.
