Always a bridesmaid and never a bride? If that's the case, then you have probably racked up a fortune in bridesmaid dresses you will never wear again!

Casey has seven bridesmaid dresses totaling up to $2000 -- and they're just sitting in her closet! Rach puts her buddy Gretta Monahan on the case to reinvent Casey's dresses into some fun, flirty and wearable pieces.

Want to turn your old dresses into something you can wear again? Check out Gretta's tips before heading off to the tailor.

• Hit up someone who knows how to sew. "It can be a friend or relative that's willing to help you out," says Gretta. "But if you don't know someone, many cities and towns have local seamstresses or tailors or even dry cleaners that can do what you're looking for." Before they pin and cut, make sure your get an estimate or quote to find out if it's worth it for you to reconstruct the dress.

• Look at the fabric before tossing it out. "Even if you think the overall look of a dress can't be saved through sewing or if the dress is damaged, see if you like the fabric, you may be able to make something else out of it," Gretta advises.

• Leave some extra fabric. With most of these dresses you will take several inches of the length, but always remember to leave some in the hem so that you can add length back if you need it.

• Customize in the details. Use that extra fabric to create a matching purse, belt or scarf that can help dress the piece up or down.
