I used to work in a storeroom and had to wear thick big trousers, boots and a jacket, and after a while got used to it but one day when I wasn't needed in the storeroom I decided to wear something more feminine. If you wear storeroom clothes for such a time it makes you feel like a boy and I was the only girl working there. All the other ladies were dealing with the other things and they wore skirts, high heeled shoes and looked nice. I wasn't able to do this and felt left out... So one day I decided to wear a skirt, cool boots and leave my hair down. Then when I arrived everyone looked at me, including those who didn't like me and I turned red. A female supervisor came up to me and told me off for breaking the work dress code, she said I wasn't allowed to wear boots or have my hair loose. Other girls with long hair kept it loose so I thought she was picking on me because her hair was very short. I also got told off by an older female senior staff for the way I looked. I had a disciplinary mark because of that, when I was wearing the work's dress code. Later that night I read the rules from a book that the managers gave me when I joined and as long as I wore the right colours and badge *which I did* I didn't break rules. The other rules about hair and boots was that so long as both weren't going to cause a health hazard it was fine. Somehow I got picked on for looking different than usual :stu
All you need to do is be yourself. Maybe your colleagues were impressed to see you wearing certain clothes and liked the look of it?
