Fashionista.com posted an article about 10 Bridal Beauty Splurges That Are Worth The Extra Cash, and wouldn't you know what is listed:
Eyelash extensions: "I suggest road-testing lashes about six weeks before your wedding (touch up the set every three weeks, so a bride will have fresh lashes for her wedding day). Price varies from about $150 to $400 for initial service and $60 to $200 for touch-ups. Why risk a potential Britney moment with lash strips that don’t stick, and you certainly don’t want to worry about smears or dry waterproof mascara formulas which can make lashes look brittle. A bonus with lash extensions -- you’ll have them for your honeymoon, when you’ll want to look gorgeous in bed and first thing in the morning, or in waterfalls in Hawaii where you may be frolicking, or whatever." —Gwen Flamberg, beauty director, US Weekly.
