Because that's Classic Amy, licensees to the Sonic brand have strict rules from Sega of Japan to keep Classic and Modern designs separated. So a Classic licensed product like Sonic Mania Adventures can use this version, but a modern-based product like the IDW comic can't.
Why didn't the comics incorporate this design? Idunno why but it's just better

Why did Amy take off her bottom to sunbathe, but not her top?
Jose Powell
How do you know she took off her bottom?
Daniel Myers
She's not wearing anything around her crotch?!
Eli Reyes
>Literally has almost no noticeable sports tape
At least use your eyes
Josiah Perry
How do you know? For all we know, she probably does have a bikini bottom under that towel.
Thomas Sanders
Yeah but now I want to know.
Jaxon Reed
Based on this comment I believe that she literally isn't wearing a bikini bottom, because her butt is too big to fit in one

I still don't like how Sega didn't give her toes.
