At Flying Boat Store, we want you to find the perfect fit every time you shop with us. Sizes can vary between brands and regions, so we recommend checking the specific measurements for each product. Below is a general guide covering clothing, footwear, accessories, and more. Always refer to the product page for brand-specific size charts and measuring tips.
How to Measure Yourself
Use a flexible tape measure. Measure over bare skin or light clothing for accuracy.
Stand straight and relax. Avoid pulling the tape too tight.
Key areas to measure:
Chest/Bust: Around the fullest part.
Waist: At the natural waistline (narrowest part).
Hips: Around the fullest part of your hips.
Inseam: From crotch to ankle bone (for pants).
Sleeve: From shoulder seam to wrist.
Head: Around the forehead (for hats).
If you’re between sizes, we suggest sizing up for a comfortable fit.
