You go nine months where your body takes on a mind of its own, stretching to lengths you never thought possible. Then post-partum you're still not back to normal and your ta-tas (if you're breastfeeding) now start to complicate getting dressed every day. All of this can take a beating on your style and self-image. Granted your responsiblity has now shifted greatly to more important things it's still a bit sad to look at your wardrobe.
But I'm not going to keep sounding all doom and gloom, because I'm getting my dressing groove back :)
