Just as a capsule wardrobe allows you to get dressed with ease, there are 10 staple pieces that you'll turn to time and time again throughout your twenties, whether it be for an easy weekend look, drinks with friends or for a big job interview. 

From the goes-with-everything blouse to the smart/casual shoe, these are the 10 pieces every stylish 20-something should look to acquire in her wardrobe...

1. Blue jeans you feel great in

Off-duty style calls for great denim, so hunting down a pair that you feel confident and comfortable in, and flatter your figure is a wise idea for an effortless, modern wardrobe. 

Why not black. you may ask? As black is seen as slimming and more flattering, they'll no doubt be easier to track down, so blue requires more thought. Shun trends and opt for the pair that suit you most and you'll plump for them on a weekly basis.

2. Delicate jewellery that won't break the bank

Intricate jewellery adds an interesting detail to an outfit, and you'd be forgiven this would come at a hefty price. The ever-growing roster of demi-fine jewellery brands is perfect in this case, particularly if you're keen on treating, but not bankrupting, yourself. Alighieri and Anissa Kermiche both excel at this: see their quirky pieces as a starting point for a jewellery collection you can add to over the years.

3. A flattering blazer

Whether you're interviewing for your first job, or just on the hunt for a tailored jacket that seamlessly pulls together even the most casual of outfits, a blazer is for you. 

Finding a flattering one is easier said than done, though, but once you've worked out whether you're keen on corduroy or tweed, checks or pinstripes and in what shade, your perfect one will work over a host of outfits.

4. A minimal watch 

Whether it's ensuring you're on time for your first day at a new job, or as an extra accessory for an evening out, a minimal watch is a grown-up addition to your jewellery roster. 

Casio and Cluse offer metallic options that look much more expensive than their price tags suggest, while Larsson & Jennings offer a wide selection of styles and sizes: this rose gold design would look particularly good with a navy blazer.

5. A smart/casual loafer

A tatty pair of shoes can break even the most smart and pulled together outfits, so a sleek shoe that works for a ton of occasions is a must in your arsenal. Enter the humble loafer. A slick staple that adds a classic element to modern looks but that's not to say it's boring: 2019's iterations are white or printed and textured.  

The right pair works just as well with a chunky knit and denim for the weekend, as it does with a floral midi and an oversized blazer for work.

6. An every occasion blouse 

From the office to a country wedding, to weekend brunch and post-work drinks, a pretty blouse is one of the most versatile pieces you can acquire in a modern wardrobe.

Branch out from florals if they're not to your taste: the myriad animal print options on offer this season are equally versatile options. Pair with dark denim and strappy heels for a smart/casual take, and with a silky skirt or tailored trousers for a smarter option.

7. A classic trench coat

You'll lean on a trench coat heavily during spring and autumn, so it's worth throwing a bit more at a style that you love. A classic beige iteration is the epitome of chic, while a trench with a twist - be it printed lapels, a coloured interior or in an off-the-moment hue - will also prove handy.

8. A fabulous everyday bag 

Perhaps the most extravagant must-have on this list is a great bag, though this doesn't strictly need to be a designer purchase. Whistles, LK Bennett and Jigsaw all do stylish handbags at affordable prices that are bound to stand the test of time in your wardrobe.

Should your budget stretch further, look to mid-priced designer labels such as Mansur Gavriel, Wandler and Trademark, all of which have a plethora of chic leather bags that will add a stylish touch to even the most simple looks.

9. An evening LBD

A frock that will take you to any evening event, be it Saturday night drinks with a chic jewelled flat and a hair accessory, to a family black tie do with a satin mule and a minaudiere, is a must. A black dress is a flattering versatile option: it isn't so recognisable that you can't wear it to a multitude of occasions with different accessories, and can be easily dressed up or down to suit all occasions. 

10. A chic pair of sunglasses 

As well as disguising a multitude of sins, a pair of dark sunnies add a classic style flourish to simple looks. A cat-eye style is the safest suits-all shape that never goes out of style, so if you're going to invest in a pair, it may be the wisest option. For those with fair skin and light hair, tortoiseshell is a nice alternative to black which may look a bit harsh.
