01 / Customer evidence
Start with the evidence you already have.
Review existing store sales, customer locations, website size data, marketplace reports, boutique requests, pre-launch interest and customer conversations.
02 / Colour plan
Keep the first colour palette narrow.
Use one core colour, one supporting colour and one accent only when the quantity and campaign support it. Distinguish existing colours from custom colour development.
03 / Size plan
Build the size mix from the actual product.
Consider the available size range, measurements, stretch and recovery, fit notes, cup or underwire structure, torso length, compression, garment ease and footwear sizing where relevant.
04 / Review
Use the first order to learn.
Record total quantity, selected colours, selected sizes, the colour-by-size breakdown and open fit questions. Review sell-through, returns, interest and missing sizes after the first selling period.
