The blue and off-white foldover western boots put a tall blue denim-look shaft above a pointed off-white toe. The current gallery shows the pull loops and the fold of the shaft; the listing offers one color choice and size labels 5.5–10. Before choosing a size, decide which part of an outfit should sit outside the shaft. That choice changes which measurements matter.

Choose where the fabric goes

Wide trousers over the boot: The trouser leg needs enough room at the height where it passes the folded denim. Lay a pair of trousers you own flat. Measure its inside width at the likely overlap point, double that number for the leg circumference, and compare it with the outside circumference of the boot at the same height once you have that measurement. A straight or wide label alone does not answer this: the hem could clear the toe but catch on the shaft fold.

Slim trousers tucked inside: Now the opening must hold your calf and the gathered trouser fabric. Measure your calf at the height of the shaft opening while wearing the trousers you plan to use. Ask for the inside opening circumference of your chosen boot size with the shaft in the position shown in the gallery. The listing supplies one 38 cm tube circumference, but does not say which size it belongs to, where it was measured, or whether it describes an inside opening. Treat it as a question for the seller, not as a guaranteed clearance figure.

Skirt or dress with the shaft visible: Put on a skirt of the intended length and mark where its hem meets a boot of similar height. The source lists a 40 cm shaft height, but gives no size, measuring start point or folding convention for that value. Compare the actual skirt hem with the boot gallery rather than assuming the shaft will stop at the same place on every leg. The blue shaft and off-white toe create two visible color blocks; you can repeat either color elsewhere in an outfit if you want a deliberate link.

Make a size request that matches the outfit

Request foot length and widest forefoot measurements for the selected size, plus internal shaft opening circumference and shaft height measured from a stated point. Ask whether the fold changes the usable opening and whether the listed 38 cm circumference and 40 cm height refer to the same size. The source lists a 6 cm heel, but provides no tested stretch range, size-by-size chart, outsole width or weight. A 38 cm circle on paper can help you visualize the listed number; it cannot predict fit around a calf or trouser layer without a measurement point and ease allowance.

Return to the product page to confirm the Blue & Off-White option, your size label and current price. Use the photos to judge the fold, toe and color placement; use measurements of the exact size to decide whether the trousers go over, inside or away from the shaft.
