You can try being girly even though you can enjoy your day to day life as a male by making minor changes in your routine.
Nail polish:
I used to wear a neutral nail colour to my work as this shade is so transparent and neutral that no one can hardly notice the colour and it gives a little shine to your nails. You can enjoy that feeling of nail colour and your beautiful nails. You will be safe until unless you overdo anything.
Wearing a Panty:
Most of the crossdressers will do this part. If you haven’t tried yet you better give it a shot because the fabric makes you feel so comfortable and will take good care of your boy parts. Don’t wear something with frills kind of thing to work as there is a high chance of getting caught and especially if you wear low waist trousers. Caution is very much required as no one want’s to spoil their name at workplace right?
Wearing a bra:
You can wear a sports bra or a regular bra with no padding to work or in public under your male clothes. Never ever try wearing a padded one as it creates a bulge and can be easily noticed by the public around you. It is always safe to wear a bra under your sweatshirts rather than regular formal wear or under normal tees. Colour of your bra also matters a lot as it is not recommended to wear a dark colour bra under a light colour/ see-through shirt. While wearing never ever allow anyone to pat on your back because people can easily figure out what you wear inside.
It happened to me once that I wore a regular bra under a sweatshirt and went out for shopping along with my friend (female) and we almost finished our shopping and when she was buying a pair of new shoes in footwear shop she took the support of my shoulder to try one shoe. After some time we finished our shopping and heading back to home and waiting at the metro station then all of a sudden from the back she pulled my bra strap and I was shocked. It was really a very close shave moment. Later I explained it to her everything about my crossdressing and she accepted me with a very kind heart. So, friends, be careful while enjoying your feminine side covered under your masculine side. Stay Beautiful always.
