Versace T shop shirt

Product Name: Versace T shop shirt
My sister had purchased this Versace T-Shirt through The Real Real for my baby...On web description it had said a size 5, that's why she had purchased it, but when she mailed to me, the shirt is way too big...It is more like a size 8/9 shop in little boys, not really sure because tag size was cut off...This shirt is in perfect condition though...No stains, tear, or piling...Just trying to resell for the price that she got it for and will use the money for a different BDay gift for my baby from her...Resonable offers are welcome.
