If you're uncomfortable with the thought of wearing maternity clothes don't worry.
Look for knit shorts that have a lot of give to them. Stretch pants, stirrup pants, and similar types are comfortable and look nice. As you approach the third trimester it might be difficult to find ones that fit well in the tummy without sagging in the legs. If this is the case take a few inches off on the in-seam from just inside the knee, across the crotch and down to the other knee area. Re-stitch.
Tee shirts are so comfortable it's hard to imagine nine months without wearing them. Select a size or two larger as the pregnancy passes. If you gain weight in places other than the waist try some men's styles for roomier chest and shoulder cuts. To make your own use a tee shirt that fits you well now but is only tight in the waist. Cut a pattern using the tee shirt but fan out towards the bottom while cutting. After cutting around the armhole and then beginning the side seam start cutting at an outward angle to allow more room in only the waist. Cut the front a couple of inches longer as well.
Button-down shirts are great for hanging around the house. Big tee shirts, tank tops or tee shirts with stretch shorts will give you lots of nighttime comfort.
Dress choices should be ones that hang below the knee. Larger sizes that tie in the back are cute and fit well. Baby doll dresses or ones with full skirts are perfect for comfort and style during pregnancy. Bib overalls are worn by many women while working in the garden or going on a picnic. They have buttons on the sides and straps at the top for adjusting.
If you sew you can always cut the front portion out of your favorite pants and replace it with a maternity panel. Putting the piece back in is a little trickier, though, so don't expect them to look like they once did ever again.
