Walmart has a number of stores that are open 24 hours/day. If you come home, have dinner with the family, wait for the kids to go to bed, and maybe even wait for your wife to go to sleep, and THEN you want to get pretty and go shopping, it could be well after midnight before you even make it out your door. Walmart also offers a very wide variety of sizes and appropriate styles for each size. If you want to go shopping at 2 AM and need plus size and don't want to end up looking like an old grandmother (like 96 year old), then there aren't a lot of other choices.
For those who are first coming out, a "Super-Store" is a good place to go at 2 AM because you can use the fitting rooms without anyone making a fuss, and you can actually try on the clothes before buying them. When you get to larger cities in the north, you see more of these types of stores, such as Fred Mayer in Anchorage Alaska, or Mier in the midwest. Walmarts are all over the country, and pretty much any city with over 1/2 million people has at least one WalMart superstore. There is usually such a store less than 30 minutes away.
Do the fashions inspire - heck no! That can be an advantage though. There are more of the clothes that will make it easier to "Blend", to look just like the other 100 women on the mall, rather than so good looking that you are either a hooker or a drag queen. Nothing wrong with being a drag queen, if that's what you want, but if you want to just be able to walk around in a shopping mall, or have dinner at a restaurant, you probably want some clothes that are nice, but as ordinary as the clothes other women wear on ordinary days.
