Size Guide
At Siempre Original, we work with an on-demand printing system, we personalize the garment exclusively for you when you place an order.
For this reason, it is very important that you choose the correct size.
T-SHIRTS AND SWEATSHIRTS
To make sure you don't choose the wrong size, it is always advisable to take, for example, your favorite t-shirt or sweatshirt and measure it as follows:
1. Lay it flat on the bed, stretched out. Use a tape measure to measure its width, from armpit to armpit.
2. Now measure the height of the t-shirt from the neck down.
3. With this height and width information, check the size chart (for the specific garment model you want) for the measurements that are closest to yours.
* Measurements may vary by a few centimeters. If the size you are ordering seems too snug, we advise you to always order one size up to be safe.
* Our garments are unisex, so they run larger than women's clothing. Women should typically choose one size smaller than their usual size.

CAPS AND HATS
Caps and hats are one size fits all, but if you want to make sure it will fit well, measure the circumference of your head with a non-stretch tape measure. Place the end of the tape on your forehead and wrap it around the rest of your head, keeping it above your ears. Hold the point where the tape meets the other end, lift the loop you've formed over your head, and record the measurement.
