A shirt dress is a perfect item to pack on most holidays or even work travels. They are very versatile and can be dressed up and down as needed on your trip. You can use it as an outfit (dress) or part of an outfit by teaming it up with a T-shirt/singlet and a pair of jeans. I have also seen a few girls who wear them with leggings as you would do with a kurta.
Talking about new moms and would be moms, I do know that not all of you are breastfeeding but some of you are or will do at some time in the future, a shirt dress has the easiest access ever.
Even if dresses aren’t really your thing, a shirt dress is always a good place to start. They are classic, easy to wear and very versatile.
