When shopping for underwear, do you often get confused by the complicated sizing system? Even if the size is exactly the same as before, this time you feel it's not quite right. Either the shoulder straps slip off, or the cup doesn't fit properly. Actually, it is something related to Bra Sister Sizes. Today, let's reveal the secret of this special phrase together.
What are Bra Sister Sizes?
Bra Sister Sizes refer to a set of bra sizes with equal cup capacities. Don't be surprised. This means that different combinations of numbers and letters have the same capacities for the cups to accommodate the breast tissue. For instance, 36F(DDD) cup and 38E, 40D, etc. all belong to the same sister size family. Bra sizes are not simple fixed standards but a proportional relationship. The capacity of the cup shape changes with the variation of the underbust size. Therefore, the same person may be suitable for different sizes in different situations.
Advantages of Sister Sizes
• Expand the selection range: Different brands or styles of bras may have variations in size design. When a certain brand or style does not have a suitable standard size, sister size can be an alternative choice, allowing consumers to have more chances to find bras that fit their body shapes.
• Adapt to body changes: Human body shapes will change due to factors such as weight fluctuations, pregnancy, and menstrual periods. Sister size can meet the wearing needs of the body in different states.
• Match different dressing habits: Some people may prefer a looser or tighter feeling for the lower chest circumference. If they think the standard size's lower chest circumference is too tight, they can choose a sister size with a larger lower chest circumference; if they prefer a tighter support feeling, they can choose a sister size with a smaller lower chest circumference.
How to use Bra Sister Sizes?
• Try-on is crucial: Whether choosing regular size or sister size, try-on is an indispensable step. After putting on the underwear, check if the chest measurement fits well, neither too loose nor too tight. Observe if the cups fully enclose the breasts, and whether there are empty cups or overflows. Additionally, feel if the shoulder straps are comfortable and adjust to the appropriate length.
• Reference Brand Size Chart: Each brand has its own sizing system. Before trying sister sizes, it is essential to carefully study the size chart provided by the brand. For example, for the HSIA brand, detailed and professional HSIA Size Chart is marked on official website and product detail pages. Based on these information, choosing can minimize the chance of making mistakes to the greatest extent. Meanwhile, you can also contact the staff online to have them recommend suitable sizes.
• Try different combinations: If the initial attempt with sister-sized bras doesn't work out well, don't lose heart. Try several different combinations of sister-sized bras. The bra styles of different brands vary greatly, and perhaps a different combination will help you find the one that suits you best.
The sister sizes offer us more possibilities in choosing underwear, but they also have their limitations. Understanding and properly applying the knowledge of sister sizes, combined with the experience of trying on, and referring to detailed size charts like those of the HSIA brand, I believe you will surely be able to find underwear that is both comfortable and aesthetically pleasing, allowing you to always feel confident.
