Oak Harbor isn't exactly known for high quality, fashionable clothing (being a Navy town where Wal-Mart's a favorite), but the Casual House is a really pleasant surprise. I've been coming back for years, when I'm in the area to see family.
It's a family-owned clothing store that's been in business for over 40 years, I guess they've recently remodeled it, and brought in lots of new lines. Prices are in line with what you'd find at the Gap or at Nordstroms, with inexpensive (and cute) gifts, and mid-priced shoes. (Pair of nice heels--between $60 and $90.) Prices were pretty reasonable for high-quality stuff. Sure, it's higher that Wal-Mart, but you can wash stuff from here and it won't fall apart like Wal-Mart stuff does. The Casual House clothing I have has lasted me for years.
They have lines that range from Eliene Fisher to Worn Jeans, Kenzie (great for teens and young women). I like the Soft shoes and BCBG Girls shoes they have.
The staff is really nice, and they're really helpful in finding stuff. While I was there, I saw them help a middle-aged, worried husband find the sweater his wife really liked, for her birthday. He was out of the store in a couple minutes, looking much-relieved.
The store is located in downtown Oak Harbor, next to a few other cute home furnishing stores and a cafe. When I'm back in Oak Harbor, I'll come back.
