The "wife beater" as I call them are by far my favorite article of clothing. I didn't start wearing this beauties until I was pregnant with Lu2 and now they are an almost daily part of my wardrobe.
I started wearing them because you can hardly buy a shirt that covers up the "goods" let alone a shirt that allows you to bend over with out giving the world a peep show. Come on people most pregnant women have small children, we need clothes that allow us to bend over in and not expose ourselves. They are long too and keep the stomach covered, after a few kids nobody wants to see the old stomach hanging out. These trusty beauties also can take a pulling and tugging that comes when you have a toddler that is trying to scale your chest to see up and over your head. They also make great pj's, kind of sexy (okay not really) but very comfy.
I bought a few tanks from the womens department of the store but they were obviously designed my men who like to see lots of cleavage they were much lower cut. These will be part of my wardrobe for many years to come too bad it took me so long to find out about them.
How about you do you have a favorite piece of clothing?
