Modest Swimsuits

I am having trouble finding a swimskirt. I would just forget swimsuits altogether because I really don't swim anyway, but I have to get in with my sons, ages 2 1/2 and 1, this summer. I wouldn't say that I am picky, but I do want a skirt that is longer than mid-thy. The only maternity skirts I have found are short and therefore not modest at all. I was just wondering if anyone has advice on what to do or where to shop?

The dress dare is going fine for me. The chilly weather in Southern California was challenging, but I stayed strong and wore my dress and leggings proudly. I wake up in the morning looking forward to what I am going to wear that day even though I only have a few choices. The only reactions I've seen are definitely positive, mostly compliments from my husband and friends about my cute outfit for the day. I can't say that I will wear skirts or dresses everyday from now on, but I think that they will become more of a normal wardrobe for me especially when it is warm.
