Our onesies are crafted from 100% Cotton Gerber Brand fabric, featuring a lap shoulder design for easy removal, especially during messy changes. You can request unlimited custom designs by emailing ohsocraftycustoms@gmail.com after your purchase. Please allow 48 hours for us to receive your email and create a mock-up. Once you approve the design, your order will be processed and shipped the next business day. Note: Our HTV (Heat Transfer Vinyl) designs come in various colors and require proper care to ensure long-lasting wear.
