Women's European scrub hat is made of quality cotton fabric, with toggle adjusted elastic in the back for a sure fit. It is slightly pleated around the hat for a more tailored look. Inside seams are all serger finished. (DESIGN PLACEMENT, toggle size, color and shape may vary). Fabric has been prewashed to prevent shrinkage. Machine wash cold. Dryer fluff, line dry. Iron touch up if necessary. Experience..... Hat is professionally constructed by a very accomplished seamstress. 45+ years of sewing experience. I have worked with and have been taught by Greek, German, Polish, Korean, Vietnamese, Italian and American tailors for 20+ years. Computerized commercial embroidery also...done with a 12 needle machine...Alterations, Tailoring, Wedding Dress making and more. Probably the most professionally constructed scrub hats on Etsy. Please read some of my reviews as to the quality of my hats. I welcome any questions you may have.
