Want to buy Meghan Markle's pastel shirt? Get the look for £85

Meghan Markle, the Duchess of Sussex, has had a series of bad publicity because of the recent private jet fiasco. However, the former "Suits" star sent fans into a frenzy when she made an appearance in an Instagram story on @SussexRoyal. Using the popular social media platform, the 38-year-old gave a sneak peek into her upcoming capsule collection.

The Duchess made her Instagram story debut and has given fans a preview of her new fashion venture. In the video, she is dressed in a pastel blue and white striped linen button-down shirt.

The shirt is from online brand "With Nothing Underneath" and is priced at £85, as per Hello. The classic shirt is likely to sell out quickly due to the "Meghan Effect," something that stems from a similar phenomenon brought about by Kate Middleton. Fashionistas who want to emulate her style need to grab it quickly as it is still available to buy in sizes XS to L. Warning: It may sell out fast.

The shirt is inspired by classic menswear styles, but adjusted for women. The classic boyfriend style has been reimagined for the boardroom or the beach. The linen shirt is a must-have for summer with its loose fit.

The Duchess left her famous hair in a loose and relaxed style. She can be seen chatting to the photographer and hugging models in the video clip and smiling.

The mother-of-one posted a behind-the-scenes Instagram video of her latest collaboration with Marks and Spencer, John Lewis & Partners, Misha Nonoo and Inside Jigsaw for her charity, Smart Works. She is the patron of the organisation that helps unemployed and vulnerable women get back into the workforce. She was present at the photo shoot of the capsule collection.

Prince Harry's wife surely knows how to work casual chic. She paired her WNU linen shirt with skinny jeans and nude high heels by her favourite footwear brand Aquazzura.

The shirt can be worn tucked into high-waist jeans or trousers to nail the look. Just add a smart slim belt and you would be good to go.

If you want similar but cheaper designs, there is a plethora of high street alternatives. Marks and Spencer has the Curve Pure Linen Oversize Striped shirt at £13.75. French Connection's Bega Dip Hem Shirt in blue is priced at £25, and the Emma Willis Stripe shirt at £28.
