International shopping is easiest when you treat the final price as product plus shipping plus possible duties. A low item price can still become expensive if shipping is slow, split across multiple parcels, or difficult to track.
Sizing is the second major risk. Always compare measurements against a garment you already own. Letter sizes are not consistent across brands, cuts, or regions, especially for oversized and cropped streetwear.
Return policies matter before you buy, not after. If a product is final sale or international returns are expensive, be stricter about measurement checks, color expectations, and whether the item is versatile enough to keep.
