It depends on places you want to go to. You can wear anything but it’s good to wear something appropriate. Buying is not important, you can make yourself presentable without spending a single buck. You can make yourself extra special from head to toe using your own effort, that will make you look different if you know how to mix and match your old clothes.
It’s fun to make your own style and trendy look, you can wear attractive blouses or tight jeans to pair with or colorful dress would also be good. All you have to do is to check your closet, bring out all attractive items and accessories. I’m sure you’ll find something that fits you well. Focus to change everything like your hair style because your hair is your crowning glory that will lighten up your face and the clothes you are going to wear will change the whole of you. You can pony your hair to look young and girly, wear attractive head bands or pretty hair clips. Soft and wavy hair is also good or, just a straight hair look.
Being beautiful and presentable is good to look at. I’m sure, you want to have a photo collection of the event and do the close-up selfie shot afterwards. I remember a friend of mine, She hates to repeat the same clothes that was already photographed earlier. It was an expensive set-up to change all the time. Just enjoy the day with your escort, Make this day a day to remember.
