Mango – Best Business Casual Fashion Choice

  • They carry a lot of items in recycled polyester, organic cotton and Lyocell
  • Weekday is available in stores and online. Disclaimer: I prefer online as I never quite liked the look of their stores, maybe I am just too old for it!

    These are lovely recommendation! I personally love the outfit you pick from Arket since I’m a big fan of black and white outfit combo <3

    I don’t buy many clothes these days, ever since I began my minimalism journey, but some of these picks are really beautiful x

  3. Lauren says:

    I have only heard of H&M and maybe mango. But it’s great there are other brands out there. I think Zara is another great one with lots of different style ideas. Thank you for sharing lovely!

  4. I on Image says:

    Yes please do! There’s a lot of really lovely items. I can imagine you’d find some cool stuff at Monki for example. Have a wonderful December Karalee xx

  5. I on Image says:

    Thank you Lisa! Dressing from the waist up is the thing in 2020. You can rock comfy leggings or jeans if your top is in check. Think about nice accessories like necklaces and scarves to spice up the items you already own xx

  6. I on Image says:

    That’s great to hear Amber! I also found really nice things at H&M for myself and for my personal styling clients who now shop online with me xx

  7. I on Image says:

    Happy to hear that you found my post helpful Lauren! I like H&M too and some of their stuff is really good quality. For example those shirts that I linked are great xxx

  8. Lisa's Notebook says:

    I love that you’ve chosen some retailers for us curvier ladies, thank you, Jenni! It’s been a while since I’ve needed any workwear as I’m a remote worker and don’t have meetings to go to but I could do with some new tops for Zoom calls 🙂

  9. N says:

    Thank you for sharing, casualwear really took the lead in our new slower life pace, this is great!

  10. I on Image says:

    True, it’s time that men got more options too. Especially color palettes for men tend to be quite limited. Thank you so much for sharing my link, hope your partner likes it. Have a lovely weekend xx

  11. Unwanted Life says:

    Women have so much more variety when it comes to fashion, I’m often jealous of that. Men’s stuff is often bland and the range is limited. I had to share the Arket bag with my partner as it might be something they’d like

Chime in... I'd love to hear what you have to say!
