Feel akward after really embarrassing situation?

parents work me and my brother was out for school.we have a privacy fenced in pool in our back yard i was out tanning by pool he had 2 friends over they decide to swim after seeing me by pool. my brother 2 friends was in pool and my brother was aggrivating me i go to push him in and he went to grab me and pull me in with him as he was falling. when he went to grab me to pull me in i jumped backwards he grabbed by my right hip and tore my bottoms off it tore the strings and the seam and messed them up and pulled them off. i quickly walked over and got the towel i was laying on when i was tanning to wrap around me but they seen me bottomless for like 20 to 30 seconds. now i feel kinda akward when i see these people again considering the fact my brother has them over about every weekend? this accident happened like 2 weeks ago and now 1 of the friends are over that was there during this accident and we all was gonna swim again and he made a comment are you gonna get naked this time? he was joking around but it made me feel akward? how do i make this accident less akward to be around these people?
