I’ve always gone by the rule, if it looks good on the bottom, keep that style! Once I find a good bottom, I want to get a couple- especially if they come in the bright and bold colors that are in style this summer! I love mixing and matching different tops with my bottoms. It’s just something fun I’ve always done 🙂 Here’s my second attempt on Polyvore (didn’t really like this one as much, but o well. Practice makes perfect!)

Now I just need the body to go with these great styles!
It’s been years since I wore two piece, and a couple of years since I even wore a bathing suit…sigh…but I love your rule. Hugs
