There is a huge difference between building a wardrobe and buying clothes. "Buying clothes" is one of the biggest pitfalls in fashion. When I say buying clothes I mean investing in pieces that won't yield the results of a functional wardrobe. These are usually trendy pieces and fast fashion items. These items will be out of style before you can get them out of the dry cleaners. LOL so why invest a ton of money in them.
A wardrobe is built on basics pieces, pieces you love and adore and a few trendy items. Notice the first thing I said was basic pieces and the last thing I said was trendy pieces. Before investing in anything, invest in the basic. You get a better return on investment and style wise it makes more sense.
