Off shoulder outfits scream “sexy” while still being classy. That “peekaboo” show of flesh without being overt gives off this classy vibe.
They come in different styles. While some keep the showing if flesh at just the shoulders, others decide to show their legs, arms and other body parts.
The important thing is that one must keep the attention of the eyes to the shoulders and having too many body parts showing may defeat the purpose of the outfit.
