Two anime tees, one sizing question
The Megumin T-shirt from Kono Subarashii Sekai ni Shukufuku wo! and the Bocchi the Rock! Ikitte Sumimasen T-shirt are both COSPA releases with the same listed measurements and size range. That makes the choice less about fit and more about which design you want to wear. Still, the shared sizing note matters: Japanese T-shirt sizes typically run a half or full size smaller than Western sizes, so check the chart before you order either one.
What the listings confirm
- Kono Subarashii Sekai ni Shukufuku wo! Arch Wizard Megumin T-shirt Sumi: COSPA sizing guide lists length, width, and sleeve measurements for sizes S through XL. The listing notes that Japanese T-shirt sizes typically run a half or full size smaller than Western sizes. Use the provided measurements to compare against a shirt you already own, rather than assuming your usual Western size will match.
Kono Subarashii Sekai ni Shukufuku wo! Arch Wizard Megumin T-shirt Sumi - Bocchi the Rock! Ikitte Sumimasen T-shirt Indigo: The Bocchi the Rock! T-shirt uses the same COSPA sizing guide and the same note about Japanese sizes running smaller than Western sizes. Because the sizing guidance is identical, you can apply the same measurement check to both shirts.

Price and design: the practical differences
At catalog price, the Megumin T-shirt is USD 15.24 (compared to USD 24.99), while the Bocchi the Rock! T-shirt is USD 16.74 (compared to USD 24.99). The difference is small, so let the design decide. Megumin appeals if you like KonoSuba's arch wizard and a darker, sumi-style print. Bocchi the Rock! suits fans of the show's indigo colorway and its title lettering. Both are casual tees you can wear with jeans or layer under an open shirt.

How to choose your size without guessing
The listings do not provide a size conversion chart beyond the measurements and the note about Japanese sizing. To pick a size, measure a T-shirt you already like across the chest and from shoulder to hem, then compare those numbers to the COSPA guide for each shirt. If you are between sizes, the note suggests sizing up may be wise, but the final call is yours based on the measurements. Neither listing includes care instructions, so follow the label on the shirt when it arrives.
Which tee fits your otaku wardrobe?
Choose the Megumin T-shirt if you want a KonoSuba piece at a slightly lower catalog price and prefer a sumi-inspired look. Choose the Bocchi the Rock! T-shirt if the indigo color and the show's title design appeal to you more. Both share the same COSPA sizing approach, so your decision comes down to fandom and color. If you are building an otaku wardrobe, either shirt works as a casual staple; just verify the measurements first so the fit matches your expectations.
