As we’ve already mentioned, it is important to welcome adulthood in style. After all, lots of people see fashion as a way of expression, a tool to help them show the world who they are and make a statement. And nothing makes a statement as good as a georgeous dress. That is exactly why, if you’ve chosen to wear a dress, you should be very careful in your selection. Of course, you should base your choice on the type of party you are going to have. If it’s going to be in a bar, then a cocktail dress is your best bet. On the other hand, if you are going to have a garden, or at home party, then you might wear something a bit more casual. Always coordinate your outfit to the venue and time of the party you’ve chosen.

Printed, flowy dress for a garden party or a brunch

If you are not very keen on big parties and going out to bars, then a simple brunch or a garden party at home, might be great. Some people might think it’s boring, although it can actually be a lot of fun. So, if that’s the route you’ve chosen, a nice flowy dress can be your best option. Choose one in a bright color or a cute print, which is going to set you apart from the rest of the guests. Let your hair flow down in big waves to give yourself a more casual look and finish off the look with a pair of platforms or even sneakers.

Bright color and a cute print are the perfect garden party attire combination

A little black dress for the perfect birthday night out

Is there anything better than a little black dress? We think not! It is classy, elegant and something that every woman should have in her closet. So, now that you have officially entered adulthood, you might as well welcome it as a grown up woman, wearing this classic look. The good news, of course, is that black dresses come in different versions. Your options are endless. First choose the length of the dress, once again depending on the venue you’ve chosen. Then, choose the shoes – if you want to be more comfortable, you can wear boots or heels. On the other hand, if your birthday is during the summer, you can choose sandals with thin straps, just like Bella Hadid.

Non standard 21st birthday outfit ideas

Well, the outfit ideas we’ve covered so far are quite standard and popular. Chances are, most women are going to be wearing a dress for their 21st birthday party. If, however, you want to be a bit more innovative and think outside of the box, there are a few things you can try. For example, you can take some inspiration from the 90s or 2000s and go with a streetwear inspired outfit. On the other hand, you can follow the newest, most popular Instagram trend – catsuits. Yes, you have to be very comfortable in your skin to wear a reavealing catsuit, however, we believe that you should definitely be super confident and love yourself. Especially on your 21st birthday.

Casual 21st birthday outfit ideas

When we are talking about casual, that doesn’t mean you should wear jeans and a t-shirt. Casual outfits, however, can be just as gorgeous as any other outfit. If, you want to be more comfortable and wear something more low key, then we have a few propositions for you. For one, jeans make a great base for a nice evening outfit. Pair them with a gorgeous crop top, a bralette or a corsette and finish off the look with a pair of heels. Does this seem casual to you?

Another more casual option is a skirt with a crop top or a blouse, tucked into the skirt. This outfit isn’t as casual as the one with jeans, but also isn’t as extra as a dress, for example. The good news, when it comes to wearing a skirt, is that you can pair it with heels, sandals, platforms and even boots. And, the best news is that if you are out dancing the whole night, having a pair of flats or even sneakers in your bag isn’t that bad of an idea. And it will go well with both jeans and a skirt.
