Revamping your wardrobe can be an exciting venture, but it can also lead to overspending if not planned well. Here are some tips to keep in mind to make this process more cost-effective:

1. **Assess Your Current Wardrobe**: Before buying anything, sort through what you already have. Identify what fits well, what suits your current style and needs, and what items are missing from your collection. Make a list of the essentials that you need. 

2. **Plan a Budget**: Decide how much you're willing and able to spend on your wardrobe before you start shopping. Stick strictly to this budget.

3. **Quality Over Quantity**: Instead of buying several cheaper items, invest in fewer but higher-quality pieces. They may cost more initially, but they last longer, giving you better value for your money.

4. **Buy Versatile Pieces**: Purchase clothing that can be mixed and matched with many different items. Versatile pieces like a classic white shirt, a pair of well-fitting jeans, or a black blazer can be styled in multiple ways for different occasions.

5. **Shop During Sales or Use Discount Codes**: Take advantage of seasonal sales, clearance items, or discount codes. You can often find great deals during end-of-season sales, Black Friday, Boxing Day, etc.

6. **Look For Timeless Styles**: Trends come and go, but classics always remain. Buying trendy items mean you may only wear them for a season. Instead, opt for classic cuts and colours that you can wear year-round and for years to come.

7. **Consider Second-Hand Shopping**: Thrifting is not only a great way to save money, but it's also environmentally friendly. You can often find high-quality, unique, or designer pieces for a fraction of the original price.

8. **Care For Your Clothes Properly**: Read the care labels and treat your clothes accordingly. Some clothes may last longer if they're hand-washed or if they're always hung to dry. By simply taking good care of your clothes, you extend their life and save money in the long run.

9. **Don't Shop Impulsively**: This is perhaps the most important rule. Always ask yourself if you really need this item and if it matches at least three other things you already own. If not, it's better to skip it.

Remember, the goal of a wardrobe overhaul isn't to buy as much as possible, but to curate a collection of items that serve you well, make you feel good, and last for a reasonable amount of time. Happy shopping!
