A combined label such as Small–Medium is one offered size, not two separate sizes in the package. For HDE's Cute Cat Short Sleeve Sleep Dress, the listing directs shoppers to choose by bust measurement. Read the numerical range for that particular style before deciding whether your usual letter size applies.
Work through one chart entry
The short-sleeve Cute Cat sleep dress lists S/M for a 34–39-inch bust, L/XL for 39–45 inches, 2X/3X for 46–52 inches and 4X/5X for 53–59 inches. These are the listing's body-measurement ranges, not measured flat garment widths. Do not halve them and treat the result as the width of the nightgown.
For example, a 42-inch bust falls within the listed L/XL range. That gives a chart-based starting point; it does not certify the fit at the shoulders, hips or hem. The product is described as oversized, but that word alone cannot tell you the exact extra room in inches.
The boundary cases are worth noticing
At exactly 39 inches, the displayed ranges overlap. Both S/M and L/XL include that endpoint. The listing does not provide enough information here to promise which one will give you the ease you prefer. Ask for the relevant garment measurements rather than automatically choosing the larger label.
Between the printed whole-inch ranges, do not invent a rounding rule. For instance, 45.5 inches is not explicitly covered by “39–45” or “46–52.” Confirm the intended sizing guidance before ordering if your measurement falls in a gap. This is a limitation of the displayed chart, not a problem with your measurement or body.
Matching cat graphics do not make matching charts
The long-sleeve Cute Cat cotton nightgown has a sleepshirt shape, long sleeves and cotton construction. Its selector currently offers Small–Medium, Large–X-Large and XX-Large–3X-Large. The similar artwork is not evidence that the short-sleeve bust ranges transfer to this garment.
Check the long-sleeve product's chart and ask for clarification if it does not answer the measurement you need. Our general plus size fit guide can help you organize measurements, while the individual style's information remains the purchase reference.
