Two points I would like to make here. Having a hard to fit size creates a situation where you either get frustrated and give up on fashion and style, or you get obsessed and become possessed by the hunt. I am one who is possessed. I'm clearly not plus sized because I wear a 4 or 6 in most items, but it's still hard for me to find things that fit. My big fit issue is my height. You may not think height is much of a fit issue but it really is if you want to appear professional and covered. Sleeve lengths are almost always too short for my unusually long arms; hem lengths on dresses and jeans too short for my long legs; darts on blouses fall at the wrong place; my torso is long, my rise is long. However, I'm not really tall enough for tall sizes and I'm too tall for regular sizes. Additionally, many big brand companies that make tall sizes do not make them small enough to fit me. Tall sizes are proportioned for larger sizes, not small so they are just too big for me. All this leads to my obsession with shopping and finding things that fit. It's work, it's hard, and the clothes that end up fitting tend to be higher end and much more expensive than those that I should be able to find in my local retail stores if I were an "average" retail size. My size is not typically available on the racks or shelves at the local mall. However, there are things I can hunt for. It must be very frustrating when there is even less available.
My second point is this. I have accepted that I need to shop online because I have fit issues, and am not like the majority of the retail population in my community. I'm not even sure that my size would be readily available if I were to shop in a big city. What is my size? It isn't really a size, it's more of a proportion issue right? I need clothes that are sized and proportioned a certain way.
