ACBuy Size Guide: How to Measure Before Ordering

Sizing is the number one source of buyer regret in the ACBuy ecosystem. Spreadsheets list sizes, but factory variance means a 'Large' from one seller measures 58cm chest while another seller's 'Large' measures 54cm. Shoes listed as 'US 10' might fit like a US 9.5 or a US 10.5 depending on the factory and batch. In 2026, the only reliable way to get the right fit is to measure your body and your best-fitting clothes, then compare those numbers to agent-provided flat-lay measurements. This guide gives you the complete measurement framework for every category: shoes, tops, bottoms, outerwear, and accessories. Follow this process and you will eliminate 90% of sizing errors before you even place an order.

Category-Specific Sizing Notes

Shoes: Most rep sneakers fit true to size for Nike and Adidas, but some budget batches run half-size small. Always check the spreadsheet size chart and read the notes column for batch-specific sizing alerts. Add 5-10mm to your foot length for toe room. For boots or shoes with thick insoles, add another 5mm. Tops: Oversized fits require adding 4-8cm to your usual chest measurement. Cropped fits require subtracting 5-10cm from standard length. Boxy fits add width without adding length. Bottoms: Raw denim shrinks 2-3cm on first wash — size up or account for shrinkage. Joggers and sweatpants with elastic cuffs fit more forgivingly than chinos or jeans. Outerwear: Add 4-6cm to chest for layering room. Puffers need more room than bombers because of bulk. Trench coats and overcoats should fall 5-10cm below the knee for classic proportions.
