How about booking a visit for your birthday girl -- and a few of her close friends -- for manicures and pedicures more at a local spa? After all, who doesn't like a little pampering, birthday or not?
Stay a little more budget friendly (especially if you plan to host a bigger group of girls) and transform your living room or kitchen into a spa for the day. Stock up on comfy pillows, candles and cucumber water. (Don't forget to save some cucumber slices for the eyes!) Use fashion and style magazines for makeover inspiration.
And another perk of an at-home spa party: Turning it into a sleepover.
