We do not manufacture garments and are not responsible for the sizing of the products. L Michelle Events & Design is only responsible for the decoration of the garments. Sizing varies from brand to brand and garment to garment. We offer size charts for all products. All size charts can be found on the product detail page as well as the Sizing Charts tab. We are not responsible for any shrinking of the garments. Polyester blends are more resilient to shrinkage, and we offer pre-shrunk cotton garments which will be listed in the product description. Please choose sizing carefully based on the sizing charts provided.
