To wear the Otis Dress, simply slip it on over your head. The tie at the V - neckline can be adjusted to your preference for a more personalized fit. You can wear it on its own during warm days or layer it with a light cardigan when it's a bit cooler. When it comes to care, machine wash it in cold water with like colors to keep the white fabric looking fresh. Use a gentle cycle to avoid any damage to the puff sleeves or buttons. Hang it to dry to prevent shrinkage. Iron on a low - heat setting if needed, and be careful around the tie and buttons.
