I am a student and also a shopping addict, especially when all of the Autumn clothes come out. This means that I also have kind of nailed where to find cheap clothing / make up and it is only fair that I share it here! You can click the screen shot of the website to get to the site!
I always, without fail find clothes I like on the forever 21 website. They seem to always have sales on and the delivery isn't crazy money either. I recently made a post about an Autumn jumper I got from Forever 21 which you can find here!
Boohoo is another of my favourites, they always have great sales and also almost always have either free delivery or next day delivery for £1! Almost all of my wardrobe is from this site, they sell great basics as well as quirky bits!
Fragrance Direct is one of the best things that has ever happened to my life, honestly. It is a life saver! You can see from the screenshot that I currently have 6 items in my basket and it is only coming to just over £7. It's crazy! They sell cheap but genuine fragrances and make up. I have got so many nail varnishes from this site, especially the essie ones that are only around £2 each when they are normally £8! I recommend it to everyone, especially for christmas shopping (which is coming around pretty fast!). Postage is only about £2 as well which is amazing.
Let me know if you use any of these sites already and if you are going to look into them more now. I'd love to know!
