I was browsing online at Old Navy for my boys and decided on a whim to buy this tank. It's on sale for $10, and I think I got an additional 20 or 30% off of that, so I figured at the very least it could be a layering piece. I'm so pleasantly surprised by how cute this tank is! It's super comfortable and has such a flattering cut. It comes in several colors, and I'm planning to get a few more. Definitely recommend!
As a complete side note, I LOVE how Gap, Old Navy, and Banana Republic have integrated their sites so you can buy from all three of them in one purchase! Have you guys noticed this? What do you think? I love how retailers are trying to make the online shopping experience better (ahem, Nordstrom True Fit, I'm talking to you) because I do the majority of my shopping online.
