HOW IT WORKS Every month you’ll get a shopping list of items – a perfect mix of classic closet staples (that you likely already own) and the latest seasonal trends. Shop your closet first using the shopping list, then fill in any gaps remaining at your favorite retailer or use the shopping directory provided. With your checklist of clothing items completed, easily get dressed every day using the daily Outfit Formulas provided in your outfit calendar. SHOPPING LIST Your interactive monthly shopping list includes a description of the pictured item, a link to shop the exact pictured item, substitution notes if you’d prefer to use clothes you already have, and a shopping directory with 10+ current retailer options that are regularly updated to help fill in any gaps that may be missing in your wardrobe. CURATE CLOSET STAPLES Build a solid wardrobe foundation by intentionally reusing closet staple pieces, these are classic basic items that you can wear season after season, year after year. Every shopping list denotes which items are considered closet staples – these are items worth investing in higher quality if your budget allows. After a few seasons of Outfit Formulas® you’ll have most of your basics in place and just need to add in seasonal trends as you like. SHOPPING DIRECTORY Every item on your shopping list includes a shopping directory of retailer links for you to browse as you curate your wardrobe. Links to items at the retailers you already know and love like Target, Amazon, H&M, Old Navy, LOFT, J.Crew Factory, Nordstrom + more can be found and are updated regularly – all you need to do is tap that ‘add to cart’ button. Link options are included for petite fit, tall fit, and plus size as well – our program is for everybody and every BODY! DAILY OUTFIT CALENDAR Your outfit calendar includes an Outfit Formula to style for every single day of the year. Just tap on today’s date to view the formula and check out which clothing articles it features. Head to your closet to grab the items in the formula, which you’ll already have handy since they were the same pieces on your shopping list, and voila – getting dressed has never been so easy! Each formula also includes suggestions on how to dress the formula up or down to suit your daily events. Once you are dressed you can tap the ‘Wore It Today’ checkbox to log your outfit styling streak! PERSONALIZE AS YOU LIKE Not a fan of white jeans, sleeveless tops, shorts, or heels? No problem! Outfit Formulas® provides you with a formula to follow, rather than a specific article of clothing, which means you have the final say of the cut, style, and color for each and every item. You can follow our recommendations to a tee or get creative with your own unique style. The choice is yours! The flexibility of a formula allows YOU to decide what matters most to you when getting dressed and empowers you to focus on YOUR priorities as you curate your wardrobe. This format allows members to adapt each formula for their own age, size, body shape, budget, climate, personal style, colors, preferred retailers, and lifestyle.
