If a woman ever lets you see her standing in her bedroom either in a bathing suit or in her pantyhose, you know then that you have reached the extremely trusted stage of your relationship.
Many women feel uncomfortable in a bathing suit mainly because they don't have a positive image of themselves. Women can be their own worst enemies in this regard probably because they are far too critical of themselves. Most women are aware of their own imperfections and certainly don't need a reminder from a partner.
When a woman puts on a bathing suit she is exposing more of her body for all to see and feels extremely vulnerable. If you are a partner who feels the need to remind her of her imperfections please be aware this will not endear you to her and it only makes the problem worse with no guarantee of a fix. Do you like being reminded of your shortcomings? No, well neither does she, so "do unto others as you would have others do for you" is a pretty good motto to remember.
Women have the choice to wear a one piece swimsuit, a two piece swim suit or a bikini. The difference between a two-piece swim suit and a bikini is the quantity of material used. A two piece swim suit is not as revealing as a bikini and covers a larger area of the body where a bikini is a small swim suit exposing larger areas of flesh to public view.
A two piece swimsuit usually has a bigger pants section covering closer to the waistline and often has a short-type leg. The bra section is wider and covers a larger area of the breast. This type of swimsuit tends to suit larger women better because the bra section has better support for breasts which means they are more comfortable to wear all day.
A one piece swim suit suits the mature figure better because it is usually much more flattering. As women get older, body shape changes and even with constant care and exercise, the mature female body will never revert back to a girlish figure that looks quite stunning in an 'itsy-bitsy-tweenie-weenie' bikini. That’s just the way life is, so for women to feel more comfortable in a bathing suit it helps your self perception if you dress appropriately for it.
