Shoes: be strict with insole measurements, heel shape, toe box proportions, sole color, and fit notes. A small shape issue can change the whole look.
Clothing: ignore letter sizing until you have measurements. Chest width, shoulder width, sleeve length, and garment length matter more than M, L, or XL, especially for hoodies, jackets, tees, pants, and shorts.
Bags and accessories: inspect hardware tone, stitching, strap thickness, clasp function, and packaging weight. Women's bags, watches, belts, and small accessories can be good haul fillers, but fragile hardware ruins the value quickly.
Electronics: check compatibility and shipping restrictions first. If the listing is unclear about model, voltage, batteries, included parts, or shipping limitations, pick another item.
