wearing a bathing suit after having a baby.

I just had my little girl a month ago and it's starting to get warmer.. and my family goes swimming/camping/family trips.. and I dread wearing a bathing suit.. I have red stretch marks on my belly. I know i earned them and blah blah blah.. but I don't want people to look at me like I'm gross if I wear a two piece so I guess from now on I'm going to wear a whole piece or just wear a tshirt and shorts. 😔 anyone else feel this way? Anyways anyone know of places to get cute one piece suits?
