GOLDEN WARDROBE RULES
My shopping motto is: If you don't miss it when you're getting dressed, then you don't need it.
The trick is to think of your closet as a collection, and only shop for what's missing. Never just buy something because it's pretty or cool. Take notice of what you really need when roaming through your clothes getting ready, and make a list. This is a good way of preventing that impulse shopping, based on your feelings for that random shiny dress you just got a fleeting crush on (that you'll never get to wear). The key is to build a wardrobe where you can find an outfit for any occasion, without having to go shopping. Even if it's for work, a birthday party, camping, or a wedding. Too many of us have the "I have a hundred party tops, and yet I have nothing to wear" kind of closets. Or, the "I only have work clothes, and nothing fancy". It's all about finding that right balance.
Instead, spare the environment the pollution, and save money on buying long lasting quality items. This way, you can rather spend your money on replacing basics (Also, more left for the occasional splurge on fashion fabs).
HOW TO MASTER YOUR WARDROBE?
Step 1. Figure out who you are, and what style you like.
Step 2. What is your life really like? Do you need to be fancy for work, or wear sensible shoes?
Step 3. What flatters your shape, looks, and colors?
Step 4. Make step 1, 2 and 3 work together and for you.
It's all about figuring out who you are, what you like, and edit until you find a way to make that style look good on you.
Step 5. Get rid of the items that doesn't do you justice.
Step 6. Yes, after you clean out the unfitting and unflattering items from your closet, you probably will have to be a consumer and buy new stuff. But, this time be very selective, and think long term. Remember that fashion goes in cycles. In five to ten years those last years jeans could be the hottest thing again, so buy quality items and aim to reuse them. There are really only three good reasons to get rid of clothes.
1. It's not your shape or color (you will never wear that, so shop smarter the next time).
2. They're so worn out there is no hope for a salvage.
3. Give those previously mentioned things away to charity or someone else who will have a greater use for it (recycle).
Everything else can be reused, altered, repaired, or stored for a later time.
This philosophy is what keeps my closet fully stocked, and the reason why I haven't had to stress-buy anything new for an upcoming event (not even for Halloween) for the last three years. I actually, hardly ever buy new things other than replacing worn-out basics and favorites, and the occasional fashion find that has been on my closet's "missing list "for at least 6 months. If you can't forget about it, it's probably worth owning. If you do forget about it, you never needed it in the first place.
Also, don't forget that you can borrow clothes from friends, and vise versa. It's a good way to get a trend or an outfit out of your system, without having to buy unnecessary things.
