Care and Feeding of Your ThinkGeek Apparel
For the longest-lasting shirts, we recommend you machine wash them in cold water, inside out, and hang them to dry. If you're a renegade (or lazy and bad at planning ahead, like us), you can throw them in the dryer, but they will shrink a bit. It's what cotton does, even preshrunk cotton. Here's a directive you'll like: don't ever iron your shirt. If you have to iron it, avoid the design.
Unisex Shirts
Loose-fitting, heavy-weight cotton. A majority of our shirts are on this blank. When somebody asks, "What size t-shirt do you wear?" the measurements on this probably match up to your answer. 100% cotton (heather grey is 10% polyester), 5.3 oz.
| S | M | L | XL | 2X | 3X | |
| Chest | 36" | 40" | 44" | 48" | 52" | 56" |
| Length | 28" | 29" | 30" | 31" | 32" | 33" |
Women's Shirts
Contoured fit, stretchy, soft cotton. Most of our women's shirts are on this blank. This fit is commonly referred to as a "babydoll." The body of this shirt tapers in at the waist and back out at the hips. 100% cotton (heather grey is 10% polyester), 6.2 oz.
| S | M | L | XL | 2X | |
| Chest | 32" | 34" | 36" | 38" | 40" |
| Length | 23" | 23 1/2" | 24" | 24 1/2" | 25" |
We offer alternative blanks for ladies, one of which being what we call the "women's classic cut." Click here to see our current offerings. We also offer a "relaxed fit" ladies' tee. Click here to see the current relaxed fit offerings.
Kids' Sizing
When deciding between 24 mo. and 2T or 4T and XS, choose the latter for taller kids. If you're unsure between two sizes, order the larger one. A shirt that's too big the child will grow into, but you can't do much with one that's too small.
| T-Shirt Size | Chest | Weight | Generic Age Range |
| 6 mo. | 19" | up to 16 lb. | 3 - 6 months |
| 12 mo. | 21" | 16 - 20 lb. | 7 - 12 months |
| 18 mo. | 22" | 21 - 24 lb. | 13 - 18 months |
| 24 mo. | 23" | 25 - 27 lb. | 19 - 24 months |
| 2T | 24" | 25 - 27 lb. | 2 years |
| 3T | 25" | 28 - 32 lb. | 3 years |
| 4T | 26" | 33 - 36 lb. | 4 years |
| XS Kids | 26" | 36 - 42 lb. | 4 - 5 years |
| S Kids | 28" | 43 - 55 lb. | 6 - 8 years |
| M Kids | 30" | 56 - 73 lb. | 9 - 12 years |
| L Kids | 32" | 74 - 100 lb. | 13 - 16 years |
Size Matters Not
If an apparel product does not specify sizing (inc. hoodies, polo shirts, etc.), then it falls into the general sizing estimates above. Any apparel product that has explicit measurements specified trumps this information.
If you get your shirt and find you have received the wrong size, check out our Return policy.
