I'm also jumping on the citrus bandwagon. I'm loving anything Grapefruit-y, especially, but any other citrus-y scents are also great.
I also picked up a cheap bottle of Parfums de Coeur's Cotton Candy Fantasy, which is very yummy-smelling. This is until I can get a bottle of any of the following for my birthday:
Serendipitous by Serendipity 3
Pink Sugar by Aquolina
Dessert (Dreamy, Creamy, or Juicy)
Sweet seems to be in right now. I'm also awaiting a bottle of the not-too-long discontinued Creme Brulee by Parfums de Coeur. Mmm!
Another summer fave is a Lily-of-the-Valley classic scent by Coty, called Muguet de Bois. My mom's loved it for years! I'm also into Demeter's Honeysuckle.
I gave my best friend a bottle of BBW's Coconut Lime Verbena, but am now almost regretting it. I know she'll use it more than I, but it still smelled so yummy. I've found that S&B at Wal*Mart has a very similar scent; I think it's Coconut Lime, but it smells identical. I may pick up a small bottle for $1.50.
Can't go wrong!
Good stuff for summer.
