What to buy from ISAWITFIRST
Chosen by style editor Laura Puddy @laura_puddyCo-ords are a staple in my wardrobe and this green set has summer sass written all over it. Team with flatforms or strappy heels, both will look great.
Chosen by assistant style editor Jazzria Harris @jazzriaharrisI love everything about this top – the frill neckline, puff sleeves and it's bold orange colour. Plus, the corset shape is great for hugging curves in all the right places.
Chosen by style writer Rachael Martin @thebretonbirdA lovely lilac corset top? I'm absolutely here for these immaculate vibes. Ideal for teaming with white jeans, I'll be finishing the look with layered gold jewels and tinted shades.
Chosen by acting deputy digital editor Eden-Olivia Lord @eden_liv_lordI absolutely need this bikini set in my life it's GORG. The sleeves, the fit and the style - a vibe. I'll definitely be rocking this to a pool party in Ibiza or a spa weekend this summer.
Chosen by audience development exec Lucy Smith @luceeeeesmithI'm a big fan of pastels for summer (not florals for spring, of course) and this knitted halter dress couldn't be more perfect for me. The cheeky neckline split? Oh-so-risque. The little waist tie? Ideal for that much-sought-after clinched waist. Seriously, I am obsessed and for £30 all in? I'll take four x
Chosen by style editor Laura Puddy @laura_puddyI am all about high heels and these designer dupes are definitely on my wishlist. Perfect to dress up jeans or wear with that killer dress – these will have you looking fly all season long!
Chosen by assistant style editor Jazzria Harris @jazzriaharrisRight now I'm dreaming of a holiday and this dress would definitely be going in my suitcase. I'd wear with tan sandals and gold jewellery for a cute evening look.
Chosen by style writer Rachael Martin @thebretonbirdIf you're looking to add a pop of colour to your day to day style then give this tangerine dream a go. Poplin shirts are big fashion news right about now so get in on the act. My advice? Team with clashing colours like green or pink for a more is more look.
Chosen by acting deputy digital editor Eden-Olivia Lord @eden_liv_lordI know it's technically summer but the weather isn't screaming cute dresses so instead I'm buying this hot pink tracksuit. I'll definitely be wearing it on lazy days and it'll come in handy during the colder months...
Chosen by audience development exec Lucy Smith @luceeeeesmithI may not be able to hit up Glastonbury this year, but you can be sure I'm still going to bring those festival vibes into my summer wardrobe. This scarf top is a happy medium between your Skims-esque neutrals and your, well, glitter tits... ANYWAY, I plan to wear it with some flared jeans and chunky Groovy Chick flatforms as I hit up the clubs on July 19th ud83dude4cud83cudffb
