You can find our size chart next to the sizing options on any product page. It provides the size along with fabric content and other clothing details for the style & color that you have currently selected. Sizing and fit is a very personal opinion and therefore we do not provide size advice beyond the size chart as some people will find a looser fit more enjoyable while others may find the same size and style too large and vice versa.
Please note: Many styles we offer are gender specific however, the "Mens t-shirt" and "tank" options are sometimes ordered as a unisex option if larger sizes are needed or if the customer prefers the fit and style offered better. The youth t shirts, toddler t shirts, and baby bodysuits can be worn by both boys and girls. Truly something for everyone in the family.
We offer exchanges for 30 days if you need a different size. Our shirts are made when ordered so do not offer a money back guarantee.
Orders that ship internationally(outside of the USA) may be subject to customs processing and various country specific fees and taxes. E.g. VAT. These costs are not included and may vary depending on where items are being shipped.
Our site search allows you to find any t shirts we are currently offering. The search works best with generic and common words rather than lengthy phrases. Please note that we occasionally do remove designs as well.

Is this Entropy Happens t shirt true to size?
Some people say yes, some no. As with anything related to sizing, even this is a personal opinion. Use the size chart to ensure a best fit.

The v-neck shirts are a womens style. We do not currently offer a mens v neck option.
Is the Entropy Happens tank top for men or women?
The "Tank" option is the mens tank top option while the "womens muscle tank top" and "womens racerback tank top" are the ladies options. However, some women do wear the mens tank top so that style may be up to personal preference.
