Misssoph,
I found this on the Pearl Paradise site and hope it will help you... I have a strand of the AAA 7.0 - 7.5 CFWP strand from PP and really wish I had gone up to the 8's... Partially as I am older (50) and more full figured and think I would have liked the way the larger pearls would have looked on me. Don't get me wrong, I love the pearls I have and wear them often but I will upgrade in the near future. I'll keep the 7's as they are a great casual look on me but will go for the 8's as well.
Although I do have to say, Freshdama would probably trump the 8 mm for me...
Whatever you decide, I know you will love them!

6.5 to 7.0 millimeters
This is the size most commonly found in jewelry stores. These smaller pearls have traditionally been recommended as an idea size for younger ladies. A perfect choice for her first strand of pearls, this pearl size is often given as a sweet sixteen or graduation gift.
7.0 to 7.5 millimeters
This is the ideal pearl size for first-time buyers--pearls of this size are classic and elegant, yet not as pricey as some of the larger sizes. They are typically finished with high-end clasps. A necklace of these pearls makes a perfect gift to celebrate a special occasion--ideal for a birthday or college graduation gift, or for a bride on her wedding day.
8.0 to 8.5 millimeters
Pearls in this range are the first foray into what is considered a larger, more luxurious pearl size. Pearls that are 8.0mm in size or greater are relatively rare and consequently more valuable. This size is ideal for anniversary and birthday gifts, for new mothers, and for special occasions of any sort. These are for the woman who loves pearls--ideal for sophisticated ladies with refined and elegant taste.
