This silly gift is also practical and fun. After all, there's nothing better than getting cozy in a blanket of one's favorite food with said favorite food in hand (pizza, obviously).

If your sweetheart's sister is a beauty aficionado, rather than trying to guess which skincare, makeup and hair care product they might fancy, opt for a stylish vanity tray instead. This vintage-inspired bronze tray features a mirrored base and it feels luxurious without being overly expensive. It's so pretty we think it's one of the best gifts for your girlfriend's sister out there.

6. Streaming Service Gift Card

We're sure one of the first questions to ask your girlfriend you had in mind was to get her Netflix login—just kidding. Gift cards are good gifts for a girlfriend's sister because they're super useful, but not too specific. With a little knowledge about that special someone's sibling (and especially if you know their streaming service of choice), you can easily pick between the major players, like Hulu, Max (formerly HBO Max), Disney+ and Netflix. We say Netflix might be your best bet.

7. Nuuly One-Month Subscription

So your girlfriend's sister is a style maven (or just aspires to be one), but is on a budget. Throw her a one-month Nuuly subscription, the go-to service for renting designer and name-brand clothes at great prices. It's a cool way to gift her clothing without the impossible task of guessing her style or preference, or having to assume a size and hope for the best (basically, giving the gift of an errand).

8. Plush Robe

A luxury robe is one of those items that everyone loves and appreciates once they have it, but will rarely buy for themselves. This plush robe will make her feel like she's on a luxury retreat at an exclusive spa every time she showers or takes a bath. It's thoughtful without requiring a ton of insight into her tastes and interests, making it a great choice.

9. Trendy Cloth Napkins

Whether she's a home decor lover with a passion for interior design or just likes to adorn her space with the latest trends, Bed Thread's colorful and on-trend textiles are sure to be a hit. We love these scalloped cloth napkins (set of four) because they emulate the current home decor aesthetic taking over social media right now. Of course, even if they're trend-averse, these luxe napkins will still delight any giftee with an eye for home accents.

10. Mini Portable Projector

Projectors are all the rage now—and for good reason. Projectors offer cinema-level entertainment in a portable, miniature and infinitely giftable format. This cute little model packs a serious visual punch, has an impressive battery life and offers superior image quality without costing a fortune.

If your honey's sister has a dog or cat, you really can't go wrong with gifting them something for her pet. It's likely her fur baby already has the basic essentials in check, so opt for something that feels a bit more luxe, like this leather pet bed by Le Dog. It's not only cozy for Fido (or their feline), but it also won't clash with their home decor.

These custom family trees make a beautiful visual display, shaped like a sideways acrylic heart and etched with a modern aesthetic. This is also a great gift for your girlfriend's parents.
