definitely casual and a bit tricky [SEP] what i was expecting to get with this was not what i actually gotstill the real problem is that this hair accessory requires a lot of work yet produces only a very casual resultthe set itself consists of scrunchy with hair attached to it a small black elastic tie and some black hair clipsin order to use it you put your hair up in a bun with the elastic tie pull the scrunchy over the bun then secure it with the pins as neededthe biggest issues i had with this set were the overall quality and the difficulty of useit also will not be much help to those with very thin sparse hair because it only makes the end of your hair look longer thicker while doing nothing much for your scalp or hairlineyou also need enough hair to form a small bun to begin with which limits the number of women who will be able to wear it at allthe color i selected was a light brown that matches my hair well enough to wearthough not well enough to make it disappear into my hair style completelysince you are ordering from a photograph you have to simply use your best guess to decide what the right color for you would beother concerns include that fact that the scrunchy shed several strands of hair pretty quickly and the accessories are very chintzymore likely than not you will need want to use your own pins to secure your bun before you add the scrunch elementpersonally i had to fuss with this a lot to get it to look right and stay put however i am not naturally gifted in the art of coiffuring so that may be a reflection on me as much as the scrunchy itselfin the end i would definitely not recommend this for a formal occasion because it does look very tousled and i doubt that is something you can changeif you are someone who likes to play with your hair this might be a fun way to create the illusion of fuller hairpersonally i would rather this set either be easier to use since it would most likely be used on casual days or be more amendable to formal hairstyles so that investing the effort of getting it to look good would feel more worthwhile
