Have you ever heard of "sister sizes" for bras?

Hello everyone ♪ This is aimerfeel on the 3rd floor ♡
"The color I want is sold out in my size..."
Here's a helpful tip for those common problems when choosing a bra:
\Bra's Sister sizes "It's ✧*。/
✓Only my size is sold out
✓ The underbust area is too tight/too loose.
It's handy to remember this in situations like that.
~What are sister sizes?~
What is your bra size? Cup size x Underbust size combination
Actually, there are some cup sizes where the cup capacity is almost the same even if the size label is different.
That's the "sister size" ♡
✓ The concept of "sister sizes" is that they are "sizes with similar cup capacities."
✓Therefore, the fit will not necessarily be the same.
✓The fit will vary depending on the shape and softness of your breasts, any asymmetry between the left and right sides, the design of the bra, and the thickness of the padding.
Please keep this in mind as a reliable second choice when you're in a pinch! ✧*。
✓ Sometimes a sister size fits better than your usual size!
✓ When in doubt, try both on.
We can take your measurements and let you try things on, so please feel free to ask us!
