Retro jewelry specialist Camilla Dietz Bergeron offers the following guidelines for making ’40s jewelry work with fashions of the ’90s:

• Wear Retro necklaces with a white T-shirt, nice jacket, and no other jewelry.

• Wear double clips separately-at odd angles, on the neckline, at the waist.

• Avoid replacing clips with posts; most earrings from this era are too heavy to be worn with posts.

• Always check the size of Retro necklaces, which often are too small for the throats of today’s larger women.

• Avoid wearing suites of jewelry all at once-a dated look.

• When in doubt, go for the more tailored piece.
