Bras are a necessity for girls, but inevitable things happen when they are put on. 
1、 Shoulder strap slipping
Falling shoulder straps should be something that all girls have encountered before. Especially in the cool summer, when you're already wearing less, it's easy to tell if the shoulder straps are slipping. Generally speaking, the reason why the shoulder straps fall off is mainly due to the improper length of the bra shoulder straps. So when choosing a bra, it's best to choose one with a wider shoulder strap, which is not only comfortable to wear but also not easy to slip off.

2、 Bras always run up
Many girls occasionally run up when wearing bras, and each time they have to start pulling the bra down. The reason why bras always run up is mainly because the lower circumference of the bra is loose. There are two main reasons for this situation, one is that the size of the bra is not suitable, and the other is that the bra has been worn for too long and has lost its elasticity. When choosing underwear, try to choose a bra with a tight lower circumference, which can effectively avoid the situation where the lower circumference of the bra is loose and running upwards. 
3、 The bra button is loose
Some people may have encountered this before, just doing a backward stretch and then the bra button opens. The best choice in this situation is to wear a sports bra without a button, or a front button bra is a good choice. It can effectively avoid the embarrassment of the bra button bursting open.

4、 Shoulder strap exposed
Off shoulder straps are not considered awkward, but some off shoulder outfits obviously cannot wear bras with straps, otherwise it can easily cause awkward situations. Only a strapless bra can effectively solve the problem of exposed shoulder straps. A strapless bra not only gathers the chest, is lightweight and breathable, but also easily solves the problem of exposed shoulder straps.
