I haven't been in the bra camp that long but can see how that is possible. I look at it like shoes. A friend looked at the shelf in my garage and said," Do you really need that many shoes?" He didn't see in the house. I had work boots, snow shoeing boots, tennis shoes, running shoes, hiking boots, one high top and one low based on the terrain and trails being hiked, water shoes and booties for paddling. Dress shoes and...... Point is I can see different bra styles, colors and shaping for various activities and wardrobe. I can go on with shirts. Dress, fishing, golf, tennis T's and the list goes on.
Be comfortable, wear what and when you want is what I'm learning.
