1. A statement puffy sleeve top
Can you dress casually in jeans for a birthday party? For sure!
That said, if you want to add a dose of fun to the get-up, a statement top always works wonders.
It just makes people think you’ve given serious thought to your look while in reality you just throw on a top and that’s it!
Think of a cute puffy-sleeve top or a delightful pastel blouse that screams the right vibes.
This cyan-blue shade is everything and the quality of this top is really good. Check out the reviews!

If you want effortlessly classy vibes, a satin top always works wonders.
Whether you team it with jeans or a midi skirt, this shimmery top is sure to elevate your look tenfolds.

While a tulle skirt is definitely not the most casual thing to wear, it’s not as dressy as you think!
You can always dress it down with dark shades like black and navy blue to balance things out.

Not every tulle skirt is flattering, but this one really stands out from the reviews.
