I guess great minds think alike--when I saw the topic, I thought of the Duggar famiy, too! I'm hoping you're thinking more "conventional" conservative, though.
We're big Lands End fans in this house-- my DD10 loves their tankinis. 1-piece coverage but 2-piece ease. Plus, it's a great place to get "matching" suits--my DDs are 8 years apart in age, so it's a thrill when they can match, unlike when I was growing up, my sister and I were 20 months apart--not such a thrill!
