One of the common sights in the city are ladies in trainers or flip flops carrying bags for their 'proper' shoes and other items of clothing they would like to wear at work but not during the commute. These magic bags are like Tardis' in that they seem to have a lot more space inside than you would have thought from the outside. They are also rather large items; hard to miss, like a Tardis. Most ladies would have one of these bags and a smaller handbag, and one often finds them juggling the bags while they walk, on the escalators in tube stations, or on the tube. It seems hard to find things in them as the ladies always seem to have to dig in the bags a long time to find the items they want.
It begs the question why is clothing for the work place so impractical that one needs to carry a wardrobe with one to work in order to be presentable? For example, why do women wear shoes that are impossible to walk in at work? Is it more important to look a certain way than to be able to walk properly? Maybe I am a bit stuck in the mud but I am of the opinion that clothing that are too uncomfortable for a person to function in are not fit-for-purpose and have therefore failed the design test. If a pair of shoes is meant to be purely decorative, rather than to be worn for walking, then it should be left on display at home (or in the shop).
