I am a former soccer mom, and I honestly think this is the hardest look to pull off! There just isn't much clothing to work with! I found the things that made me feel more put-together was accessories- a cute tote bag for the days I was in charge of snacks, and the forgotten socks, etc., wearing jewelry, a bright-colored umbrella for the sun/rain, braiding my hair (something different than usual) or tying a scarf/bandana in team colors around my head. Accessorizing helps take the focus off the body, and it is fun to get creative with things you can change quickly.
