Hey I just wondering around on tumblr and found this:

It's a HUGE infodump on how to find and fit a bra properly. Lots of stuff I didn't know (that front thing is supposed to sit against your chest? huh)
Yaaaaas! Good info all around! I think I used that when I first started looking into better bras (teenage years, I had one, that cost me $150 and was beige...so boring...). Now I have many in different colours from buying online
