For starters my FI and I are only having 60 people max at our wedding, and decided on 2 attendants each.  Ultimately I have 4 close friends and my FI's sister who I would consider asking to stand up for me.  Should I ask based on who's most likely to attend (due to distance/jobs)?  Should I ask based on who's more financially able to cover the related expenses (dress, shoes, hair, etc)?  Also one is obese (to be blatantly honest) and I have no clue what would flatter her or what she'd be comfortable in. . .I've never seen bridesmaids advertised with a model above a size 6.  I understand the advice is typically to ask who you're closest to, but I consider each friend to be equally close, and I want each bridesmaid to feel and look her best.
