I guess if you feel afraid to be stung, you can wear that getup as long as you like.
The most important thing is being calm and comfortable while you work with the bees. If you are agitated, moving with lots of fast movement and jerking or shaking around, that will affect the bees temperament.
If wearing a suit makes you calmer, and more confident to move slowly and deliberately, then go with what helps you do that.
The hardest thing about working with bees is mentally accepting that you WILL get stung.
Once you have truly accepted that in your mind, you will find you don't need a suit at all. At least all the time.
There are certain circumstances where you are knowingly going in to agitate bees that no amount of calm on your part will change their temperament quickly. Like doing a removal from a house.
