The 7-8 medium sizing is the closest approximation to what should work for most but please consider the measurements listed and your intended use. The design is delightfully faded but intact, and the most noticeable stains/marks are pictured.
Two are located on the front of the shirt and one very light stain is on the back. Due to chemical sensitivities of owner, no fabric softener or stain removers have been used, so it is possible that you can lighten or even remove one or two of these. Single stitching and the manufacturers marking on the front verify the authenticity of this vintage piece SSI was for Stephen Slesinger, Inc. Who had a contentious relationship with Disney due to legal challenges concerning merchandising and other rights. Along with the added value that this hard-to-find design and its interesting history with SSI will interest a collector, the whimsical design will surely delight any young fan of Beauty and the Beast, as well!
