FAQS
To keep your Sister Store Concept pieces looking their best:
Always follow the care label. Most of our items are delicate and should be hand washed or machine washed cold.
Hang or lay flat to dry — avoid the dryer to maintain shape and fabric quality.
For special materials like knitwear or sets, we recommend gentle detergent and minimal agitation.
