It's high time we understand the importance of reducing fast fashion and make ethical fashion choices. To make things easier for you initially, let us tell you that this brand called Ikmi will do the work for you.
Ikmi is an online thrift shop that is fully stocked up with vintage/thrift pieces and if you are someone wanting to make that necessary switch, Ikmi could be the perfect place to start with. They have got beautiful trousers, stunning dresses, oh-so-pretty tops, and so much more. Much like other online vintage stores, their collection gets sold out pretty quick, but that doesn't mean you need to lose hope. Their range is not only super cool but the pieces are versatile. We had purchased their crop cardigan from here and not only does it go well with our high-waisted mom jeans but looks amazing with our denim skirts too!
Oh, and their range is pretty affordable too (starting at INR 800). You wouldn't have to worry about DMing them about details every time they drop a range either, because they make sure to put up all the necessary details on their posts.
Now, we suggest you get to shopping!
