If you're looking to update your wardrobe with some staples that can be worn at any time this summer, then it looks like Marks and Spencer has you covered.
The item in question is the high-street retailer's Cotton Rich Ribbed Slim Fit Vest Top, which costs a purse-friendly £8.50, and is currently so popular that it is the fourth bestselling item on the M&S website, as shoppers flock to buy one.
Available in sizes ranging from a UK 6-24, this simple summer vest can also be purchased in 10 different colours, ranging from black and white to vibrant pink and orange.
However, when we had a look on the M&S website, there are already three colours that have sold out online - neutral, petal pink and bright turquoise. So, we'd advise grabbing one quick before you miss out.
The cotton-rich vest features a flattering slim fit design which can easily be tucked into jeans, skirts or shorts for the ultimate casual summer fit, reports the Mirror.

Included in the M&S Collection range, it also features a neat crew neckline and thick straps that will be ideal for hiding your bra straps if you need that bit extra support.
More than 200 shoppers have left the Cotton Rich Ribbed Slim Fit Vest Top glowing five-star reviews, with them hailing the "versatile" top that they can pair with anything this summer.
One happy shopper wrote: "The perfect versatile vest top. Keeps its shape and looks really flattering with or without a layer. Lovely fabric, it’s not see-through or thin. Great price too."
A second glowing five-star review read: "Simple women’s summer vest. Goes with anything, comfortable, cool and well made.”
A third impressed fan wrote: "At last a great quality nice fitting vest top! And in a good selection of colours! Very nice soft ribbed fabric and a good fit. I’d say these are on the generous side but I don’t like very tight clothing. I have already purchased five! I wear them over my crop top for my Pilates classes. Very useful!"
A fourth added: "Such good quality and very flattering. True to size and washes really well. Dress it up or down . Great addition to summer neutrals."
Shoppers can purchase the Cotton Rich Ribbed Slim Fit Vest Top for £8.50 from the M&S website.
