[General Fantasy] I just drank a shrinking potion and my clothes shrank with me, how?

I was trying to get something in my house that I couldn't get at my normal size so I decided to take a potion I bought at my local magic shop. When I drank the potion I was honestly thinking I would shrink out of my clothes and be, well naked in my smaller size. If it had been a spell I could get it since the magic was coming from an outside source but I'm having a hard time wrapping my mind around the idea that my clothes where affected from a magic from inside my body. The few times I've heard stories from adventurers that have taken similar potions their clothes haven't fit so why was mine different? If this can be done why don't all body altering potions alter the clothes as well to fit the altered form of the person that's taken the potion?

There were no biological or physiological effects of the potion in your body.  Drinking it merely released a spell that targeted you.

The proof is in the fact that the same potion works identically on most any being, regardless of size, race, or species.  It even works on constructs, such as warforged.
