The very best lit stores, with striking window shows, might have yukky fitting rooms. Customers much like me want better dressing rooms and merchants are becoming the content. Many stores are embracing “social selling” to enhance sales.
A price reduction store within my hometown, a part of a nationwide chain, just renovated its fitting rooms. As the lights are better, and you will find more hooks for clothes, I would not provide the rooms a 5-star rating.
