I've never been much of a bag girl. Though, it seems that there are a lot of people out there who are even despite not having much of an interest in fashion otherwise. While I tend to go for quality when it comes to the majority of my wardrobe decisions, when it comes to bags I either buy vintage (which is great) or I fall into a habit of buying inexpensive bags from Target and wearing them for a year before the stitching begins to fray.
Quality bags can be a huge financial investment, but think of it as just that---an investment. Buying a high-quality bag will cause you to spend more now but it will prevent you from having to purchase and re-purchase lower quality bags every year. Plus, as with any other fashion category, buying quality is a much more eco-friendly option.
When investing in a bag, be sure to choose a label and style that won't go out of fashion, at least not for the next 10 to 20 years.
