Slim and Trim Neoprene Slimming Tank Size Large Solid Black.
Text in back of garment has worn off - hard to read and impossible to photograph the size but I believe it says Large. I compared the letter spacing to a listing with a size large and it appeared to match.
Per the side of the package image Size Large fits:
Bust 38-41
Waist 30-33
Overall in good pre-owned condition. No issues to note. Lots of useful life remaining.
Item has been cleaned per eBay policy.
