Regardless of what you do there is one worthwhile basic wardrobe list to start with. It is the list I go back to time and time again. If you have these ten items in your wardrobe you have the foundations of style.
1. LBD little black dress
2. White shirt
3. Black jacket
4. Blue jeans (skinny or flared)
5. Grey t-shirt (or black or white)
6. Black skirt
7. Jumper or cardigan
8. Pair of flats
9. Pair of heels
10. Print top/shirt
I need to update items 2 and 3. My current white shirt I have had for 7 years however it is looking a bit tired and slightly wrong as it is too structured. COS and Zara have a good selection of white shirts at reasonable prices. Zara is probably the best bet for a black jacket too in the reasonable price range with the requisite good cut style stamp too.
A capsule wardrobe is so simple and it very effective when you have a wardrobe creative malfunction. Try these simple combinations.
1 + 2 + 9 for an evening out. Wear the white shirt under a sleeveless black shift dress - it is less likely to work on a more flamboyant style but don't be afraid to try.
1 + 7 + 8 is an easy work wear look when you are mainly desk bound or want a rest from heels.
2 + 3 + 4 + 9 (or 8) is a classic look for day or night depending on where you are going. A great Sunday lunch look.
4 + 9 + 10 for a girls night out
4 + 5 + 8 supermarket shop!
2 + 6 + 7 + 9 another work wear look.
I could go on and on but the point is made you can combine and use a capsule list to make outfits and then build on this to create more outfits with a wider range of garments. But use the basic capsule to ensure that what you buy can work with other items and are versatile.
