How do you check your size?

Get your favorite t-shirt and lay it on a flat surface and follow the fit guide below. Check the size chart for each item to find the size that fits you best. Keep in mind our size charts are based on t-shirt specs, not body measurements. Allow 1/2 inch tolerance.

  • How to measure: Please multiply bust and waist by 2 to get the all around measurement.
  • Chest: Measure from left seam to right seam one inch below the armhole.
  • Waist: Measure from left seam to right seam at the waistline.
  • Length: Measure from the top of the front collar to the bottom of the shirt.

Children's Department

The industry standard for children's apparel is to use age as the size, but it is important to measure your child's clothing to be sure that you are picking the correct size. When measuring if your child falls into two different sizes then it is best to size up to ensure a better fit.

Note: Size chart is a general guide; sizes may vary according to the item itself.

Feature Glossary

Fabric Type

  • Classic Cotton: Classic interlock knit fabric. These are versatile and durable, the gold standard for t-shirts.
  • Burnout: Burnout tees use a chemical technique to dissolve certain fibers, leaving a sheer, semi-transparent pattern against the solid fabric. Burnout fabrics give a totally unique, vintage-worn look and feel.
  • Heavyweight: A thicker, heavier fabric than our classic interlocking knit. Heavyweight tees are usually made from cotton or hemp.
  • Sheer: Sheer tees are made from extremely thin, semi-translucent fabric that stretches to form-fit.
  • Soft: Soft tees are made with either higher thread-count cotton than our classic interlock knit tees or with a blend of cotton and one or more synthetic fabrics. Soft tees and softer, lighter, thinner, and often sized more snugly than classic cotton tees.
  • Super-Soft: Like our soft tees but even softer and more comfortable to the touch.

Cut

  • Classic Fit: A standard, basic-cut tee. Classic fit tees are loose around the midsection and arms and a little snugger at the chest.
  • Fitted: Fitted t-shirts feature a snugger, more vintage cut. Tighter around the sleeves and midsection than a classic fit tee, these are cut a size down from classic fit tees.
  • Slim Fit: A sleeker cut than our fitted tees, narrower around the waist and ideal for slim-built women and teenagers.
  • Plus-Size: Similar in proportions to classic fit t-shirts, but sized up for larger individuals.
  • Relaxed Fit: Relaxed fit tees are cut wider at the torso to wear loose for a light, billowy feel.

Specialty

  • Old Glory Exclusives and Limited Editions: We carry thousands of items that are exclusive hand-chosen licensed designs produced for just for us by our Music, Entertainment and Famous branded merchandise properties. These rare exclusives are only sold on OldGlory.com. Limited edition items are from a set production run; once they're gone, they're gone. Limited edition products are often of a much higher quality than typical mass-produced items.
  • One-of-a-Kind: One-of-a-Kind items are often much higher quality than typical mass-produced items. These are found in our selection of tie-dyed and over-dyed T-Shirt and apparel items, as well as many hand-made cuts and sewn items such as specialty dresses, shorts, and skirts.
