  • Durability and care: Look for durable stitching and easy washing to withstand frequent cleaning.
  • Versatility: Three-pack options and multiple color choices help rotate outfits without excessive laundry.
  • Safety features: Avoid loose embellishments and ensure any mittens or booties are integral to the design without choking hazards.
