Can the Mind Sharpener infusion be used in tandem with an Armor infusion?

One of the new Artificer infusions from Tasha’s Cauldron of Everything is the Mind Sharpener, requiring "A suit of armor or robes". There are other Artificer infusions that apply onto armor, such as the Armor of Magical Strength, requiring "A suit of armor".

Can an Artificer wear robes on top of (or underneath) a suit of armor, infuse the robes with "Mind Sharpener" and infuse the armor with another armor infusion (to benefit from both infusions and the armor’s other properties as per normal) ?
