Re: how to remove articles of clothing in sims 3

@ghostyglitch  There's no direct way to remove the articles of clothing without replacing them, at least within outfits that require those items.  But what you could do instead is switch your sims into their swimwear, then assign them something non-distracting like a white bikini or Speedo.  They should still be wearing that outfit when you switch back to the other categories.
