What does 'flowing feel' mean? Hard to say, without more context. Perhaps her long hair is blowing around her shoulders, or sliding between his fingers. Perhaps she's standing in the cool, swift river on a hot summer's day. You see, English grammar can be so exciting!!!
If you were talking about wallpaper with a flowing pattern, for instance, or the design of a piece of furniture, you might say "it has a flowing feel". This would mean "I like the flowing impression that it gives".
