should i stop wearing tank tops in public?

i’m in penang atm, and it’s super hot so i usually wear tank tops when i’m in public otherwise i feel like im melting..but i started getting some weird stares from like people in white uniforms (im so sorry i dont know who they are) and some people in public..i cover my shoulders and legs when i go to temples and some places where i know i have to dress more modestly. i dont understand why im getting judged and stuff when ive seen locals and other tourists wear tank tops as well. it it helps, the straps are about 3 cm thick, the neck isn’t too low at all and it’s not cropped. i do wear a cross necklace because i am christian but surely that shouldn’t change anything?
