My Favourite Summer Dress
This is by Pretty Little Thing.
I would forgo the accessories for this one, focusing on a bag and shoes and maybe a light jacket. The material is surprisingly durable and thick, so you will definitely have a smooth silhouette.
I picked this up for £15 I believe, with a 20% student discount (which fuels my shopaholic tendencies). They may still have it in stock, and in other shades but this collared dress/ strappy style is very popular this year. I've picked up quite a few shirts and dresses in this style.
I think this adds a touch of sexy to any outfit without bordering tacky. You can ad tights to be a bit more understated, but cleavage is minimal and the boxy style means you aren't showing off too much. I'm usually on the more conservative style, so for summer months, this would be great for nights out.
As you can see, the rest of my outfit is very simple but styling these types of dresses is very easy, so let me know in the comments if you've bought anything similar.
