Lisa, since clothing is increasingly becoming immodest do you reckon there will be a stage in the future in which some people may wear bikinis as casual wear. I know that sounds completely crazy, but thats how "style" works, around a crazy influx.
It's possible Sarah. But I think the main obstacle is that bikinis will most likely not cut it in most offices. Then there's also the price of permanent hair removal. Laser hair removal is very expensive, and you need to go for several treatments just to remove small patches of hair. Electrolysis is even more expensive, and again, you need several treatments before the hair follicles are completely destroyed.
Although waxing is less expensive compared to the procedures I listed above, I don't know how many women would really want to get bikini waxes every other week. (Sorry for being gross guys.)
On the other hand, shaving is inexpensive and works fine for a lot of women. Then again, it's not ideal for certain parts of the body.
But even now, I see women on the streets and subways wearing flimsy halter dresses and strapless sundresses in the summer. So who knows?
