Hello. How is everyone. I hope well!! 
Im looking for a bra. I have grown into a a cup. Im looking for something I can wear every day and it wont get noticed very easily if any under my tee shirts. Any help is greatly appreciated. Thank you

Hello.  Congratulations on needing a bra!  I suspect that you will get several replies.  Have you looked at the Hanes sports bras?  Walmart has several styles (front zip, racer back, etc) in several colors.  Check the labels, the compression level varies.  Some have padding that you can remove.  Walmart is convenient for those of us in the US but other manufacturers have similar offerings.  I bought one of each style and tried wearing them last November and December during my vacation times. They were comfy and those with with flat(ter) straps were not noticeable at all under my shirts.  95% of the time, I wear loose long sleeve button down shirts.  I suspect the flat strap styles would be ok under a looser polo shirt.
