Has anyone mentioned Target yet?
Great comments here from Rachylou and others about knowing the situation you're dressing for before spending money.
In a past life, I worked a job where one of my responsibilities was purchasing wardrobe items for video shoots and Target was my go-to for budget-friendly, fresh looking, camera ready clothing that fit a range of body types and scenes (from office, to medical, to at-home, to hospitably, retail, media-host, etc.). Seriously great if you're seeking to dress the part.
