Earrings are the easiest gift: no size to guess. A few pieces under $75 that work with the clothes she already wears.

If she dresses simply, give her one good piece that works with what she already wears. Earrings are the safest choice: no ring size to guess, and they show up in every photo.

Here's what we'd pick, depending on who she is.

She lives in jeans and a white tee

• Candice Triple Hoop Earrings, $50. Three small hoops in gold and silver. With a plain tee, she won't need a necklace.
• Joelma Duo Sphere Drop Earrings, $49.90. A gold stud with a silver sphere below. Easy with jeans and a blazer.

She never takes her jewelry off

• Faith Chunky Hoop Earrings, $52. Waterproof stainless steel, so she can wear them to the gym, in the shower and to dinner.
• Ashley Pearl Lariat Necklace, $59. Also waterproof. A little softer, for someone who likes pearls but not the classic strand.

She already mixes gold and silver

• Melane Frizzed Duo Metal Stud, $64. Gold and silver with a wavy texture. Small, but people notice.
• Ursula Two Tone Link Chain, $52. A chain bracelet with gold and silver links. It stacks with whatever she already wears.

She likes a little shine

• Mabel Zircon Statement Stud Earrings, $66. Sparkly enough for a dinner out, simple enough for a white shirt the next day.
