best swim suit with toddlers and babies! its true to size and covers what is suppose to be covered, bc we know we don't need those cheeky swimsuits haha! I don't have that feeling like I have to keep fixing my bottoms or top, which is the best bc thats one thing off my list to worry about while at the beach, because lets be real we got kids to protect. I am about 145lbs wear a size 4 jean and have very small chest (34A/B). I picked a size small top and medium bottom, fits prefect and everything stays put.
