So I'm taking college courses this summer and have to walk pretty far in the heat. I like wearing spaghetti strap tops and stuff, but was thinking of getting some cute muscle shirts from urban outfitters. The arm holes are pretty long so a bralette would show through the side. Is this considered too revealing?
No way! Go for it, summer is hot and it's perfectly fine for bra's (in any form) to be showing, regardless of weather. It's society that has added sex appeal to a woman's breasts, they're just a normal body part
