Hey! I need some help... my wedding is at the end of September. I am an avid runner and already, just from this last month of warmer weather and shirtless running, have my sports bra tan lines starting to reappear. my dress is sweetheart neckline and strapless with a corset back. does anyone have any suggestions of what I should do throughout the summer months to avoid have a farmers tan (from wearing a shirt while running) or have a big white X and strap lines on my back and shoulder by the end of summer? Thanks!
