Hmmm....
If I bought someone a handbag and wanted to "fill it," I would consider purchasing:
... matching wallet w/a Starbucks gc or gc to her favorite "fast" food place. (if in the budget)
... matching mini skinny with same gc as above
... wristlet or makeup bag with a few of her favorite necessities (lip balm, tube of her favorite lip gloss or lipstick, gum or mints, pack of tissues, hand sanitizer, lotion, blotting tissues, hair ties, wisp disposable toothbrushes, nail file, cute little mirror, rollerball version of her favorite perfume... obviously, not ALL of those things-- just whatever fits her likes and fits in said makeup bag!

)
... keychain
... coordinating scarf or bag charm
If she has had a rough past few months, I would write inspiring quotes, reasons why you love her, or what makes her a strong and lovely person on a business-sized card, laminate it, and stick it in the wallet or mini skinny. She may need the reminding every now and then!
