Children’s Play Pretend Firefighter Dress Up Costumes Imaginarium (red) & Tetot & Co. (yellow) The yellow costume is size 3/4 The red costume’s tags have been removed, but this is slightly larger than the yellow firefighter set. I am estimating this is a size small, but this could easily be worn as a 3/4 with a little room to grow, as well. Play condition due to some signs of wear with a few scratches & discoloration/stain spots as shown in photos - but overall they are in great condition. They have a ton of life left! Those flaws just make it more realistic :)
