I don't know if what I do works for you, but since I know a lot of women who are pregnant like myself tend to have those insecure moments about how they look, I've become meticulous about what I wear when I go out.
See, just as normal as our everyday life where we want to look pretty all the time, being pregnant doesn't give you the excuse to look haggard or ugly. Thus, the idea to do something about it kicked in... with not much to do I turned to shopping. I went out and searched for cheap or affordable clothes which aren't exactly the official maternity wardrobe required but stylish and comfortable enough for preggy ladies out there to wear.
The trick is to buy the right type of clothes, and a nick to mix and match.
What I bought most were stretchable spaghetti strap tops, sort of like this one (preferably, assorted colors as well):
and then match it with stretchable maternity leggings...
and then over it a maternity / even simple cardigans, jacket or something...
and voila! Stylish preggy in the house!
Take a look at these for inspiration:
What's best about these clothes is that, even after giving birth, you can still wear all these and still look pretty good! So, what are you waiting for? Indulge yourself and keep your mood up by pampering your appearance. Enjoy!
