Kate Spade sizing is easiest when you use the brand's measurement charts and then check the fit note for the exact style. This guide compares the size chart with pajamas, flat sandals, slides, and heels so you can decide where true to size is useful and where it is not.

Kate Spade Sizing: Does Kate Spade Run Small, Big or True to Size?
Use the chart, then read the style
Kate Spade sizing is easiest when you use the measurement chart, then let the cut have the last word. The phrase "kate spade size chart" is a sensible place to start: the women's clothing chart runs from XXS/00 to XXL/16 and uses bust, natural waist, and hip measurements, while the shoe table covers US 5 to 11 in half sizes with normal and wide widths. That is more useful than trying to make one number cover sleepwear and shoes. For sleepwear, the Macy's Long-Sleeve Notch Collar Brushed Jersey Long Pant Pajama Set has a 30.5-inch inseam; Bloomingdale's Printed Cropped Pajama Set is listed with a 25-inch inseam and called true to size. On feet, Bloomingdale's Double K Block Heel Sandals are marked true to size, but its customer-fit feedback says they run large. Nordstrom calls the Flourish Slide Sandal true to size and lists the Loop Ankle Strap Sandal in medium width. Different materials and straps matter, so a chart is only the opening move. Measure the body area or foot width that matters most, then read the note for the exact style before trusting a general recommendation.
Sleepwear is about length and ease
The pajamas and robe are a useful reminder that a size can fit well and still be the wrong length. The Long-Sleeve Notch Collar Brushed Jersey Long Pant Pajama Set has a 30.5-inch inseam and a 25.5-inch top length; it is the better reference if you want a full-length pant. The Printed Cropped Pajama Set has a 25-inch inseam and is described as true to size, while Nordstrom's Dot Pajamas are another printed option in the same category. One Bloomingdale's reviewer, 5 feet 2 inches and 130 pounds with a 36C bust, said a small felt tight and preferred medium for a roomier pajama fit; that is one person's experience, not a sizing law. The Two-Tone Burn-Out Plush Robe is relaxed and about 42 inches long. I would compare the inseam with a pair you already like before choosing, then decide how much ease you want through the waist and seat instead of assuming sleepwear should fit close.
Open sandals need a foot check
Open sandals are less forgiving to guess from a clothing size, so I use the Kate Spade shoe chart as a starting measurement, not a promise of fit. It spans US 5 to 11 in half sizes and prints normal and wide widths, which helps if you already know your foot width. The Halo Platform Footbed Sandals have a 2.75-inch wedge and 1.75-inch platform; Macy's reviews include one report that the Sandie Flip Flop Slip-On Sandals run small and another that the strap may feel long on narrow feet. Those are individual experiences, but they are worth considering before treating a half size as a fix. Loop Flat Sandals are a leather slingback with a bow detail, and Bloomingdale's labels them true to size. Nordstrom also marks the Flourish Slide as true to size in B width. If a sandal has an open toe or a single strap, check where your toes land and whether the strap feels secure; the size chart cannot tell you that. I would start with foot length, then look at the exact strap placement, especially if you are between half sizes.
Heels call for model-specific advice
With heels, the advice is more model-specific than category-specific. Treasure Embellished Dress Sandals are listed true to size, but the 3.5-inch heel makes them an occasion shoe where toe-box comfort matters; I would not order them by optimism. Loop Block Heel Sandals have a 2.5-inch block heel and a leather upper, lining, and sole, so they offer a lower heel, although Macy's marks this color as final sale. Double K Block Heel Sandals are also marked true to size on Bloomingdale's product details, yet its customer-fit summary says the fit runs large. Loop Ankle Strap Sandal is marked true to size and medium width, with an adjustable buckle and 2.75-inch heel. Those details are why I would not flatten Kate Spade into a single runs-small or runs-big verdict. Buy by measurement, then let the shape and width decide. If you are unsure, start with the product page that gives the clearest fit note and skip a final-sale shoe you cannot try on first.
