Yes, Supima cotton can shrink after washing, so follow the care label and avoid high-heat drying. Supima describes the cotton's fibre quality. It does not make a finished garment shrink-proof.
Why fibre quality does not settle fit
Supima is extra-long-staple cotton. Long fibres make a strong yarn, but a garment's final size also depends on its knit or weave, its finishing and how it is washed and dried.
Three factors
Fibre
Long, strong yarn.
Construction
Knit or weave holds its shape differently.
Care
Wash and dry method decide the result.
What protects the fit
Follow the label first. Wash and dry as the label allows, lift wet garments without wringing them, and avoid a hot dryer unless the label permits tumble drying.
Measure before the first wash
Measure chest, shoulder-to-hem length and sleeve length in centimetres while the garment lies flat. Measure the same points once it is dry. That shows the real change instead of a guess based on how it feels. Compare against the t-shirt size guide or the women's jersey tee size guide to keep the fit you chose.

Frequently asked questions
Does Supima cotton shrink after the first wash?
It can. The fibre name does not predict how much, so the label and the wash method decide.
Can I put Supima cotton in the dryer?
Only if the care label allows tumble drying.
Should I buy a size up to allow for shrinkage?
Buy for the fit you want. A larger size is a guess, not a fix.
Is Supima cotton pre-shrunk?
Not automatically. Check the product's care information for any pre-shrinking statement.
