The button for the room up sleeve is missing, but on the tag there are extra buttons. Please view ALL photos using the zoom feature to further assess the measurements and size, condition, style and color before purchasing. If there is a discrepancy in the information we've provided, please contact us for clarification. Measurements are within approximately 1/2 inch. Tag size is not always a good indicator of fit due to previous washings and wear. Please compare actual measurements with a similar piece of clothing that fits you well to determine proper fit.
