When your sister hits the 40 year milestone, give her something that's thoughtful and has a sense of her personal style. For instance, she may enjoy a sterling silver engraved picture frame of the family or even something as simple as a bouquet of flowers with a heartfelt message. In any case, for a sister's 40th birthday, give something sentimental and elegant that she can enjoy time and time again.

By 40 years of age, tastes are most likely to be refined. If your sister is a wine lover, this gift will get plenty of use. Even if she only enjoys a glass or two with dinner, you can make it special by adding a homemade coupon that states where and when the two of you will share the wine. For example, with that Merlot she likes with dinner, include a coupon saying, "This is to be shared with me and my sister on April 3rd at 8 p.m. after all the kids have gone to sleep." This gift will give you and your sister alone time together.
Personalised Picture Frame
A personalised picture frame is elegant, simple and very personal --- something she can cherish forever. Include that picture of both of you when you were younger, or the picture of you fixing her hair on her wedding day. Supplying a long-forgotten photograph makes this a gift she can always remember. For an even more personal touch, engrave a short but sweet sentiment on the frame -- for example, a photograph of both of you as children with the words, "To my best friend."
Her Choice Spa Day
Turning 40 is a big deal, so chances are you will want to pull out all the stops for your sister. Send her on a day of rest and relaxation. You can book a day of pampering that includes the services of her choice. To make it fun, do it as a Sister's Day Out event. Tag along and reminisce about old boyfriends and new careers.
