Diligent Girl and Youthful Lingerie

p1
>>Mom
>>Ran, are you sure you can buy them by yourself?

>In front of this underwear shop stands a lone girl with a stern expression...

p2
>The new work by "Sakura Trick" and "Kanaeru LoveSick"'s Tachi!
>Underwear is all the same?
>Let me show you the unknown world of underwear!
>Diligent Girl and Youthful Lingerie

p3
>Don't worry about it...
>I'm a high school girl. There's nothing to get embarrassed about...

>Hm Hmm

>Students come here normally too...

p4
>I can be diligent too.

>Ugugu...

>I wanna leave quickly after all.
>I'll just pick something fitting around here...

p5
>Now I just have to pay and it'll all be over!

>Miss, are these presents for someone?
>No, they're for me.
>I don't need any gift wrap.

>...Eerm...

>This one's C70.
>The one in the middle is E75.
>And this one's D80.

>They're all completely different sizes...
>Wha...!?

p6
>I-I'm in my growing period so I figured I should buy three different sizes...
>How agonizing is this...!?

>Miss...
>?

>That's
>a great idea!!

>One day, there was a girl we'll call A-san who wore underwear that didn't fit...
>She's started telling a story...!!

p7
>At first, A-san had no problems whatsoever.
>Then one year later, on a certain day
>she started noticing that flesh was sticking out the sides under her armpits.

>A-san was bewildered. "I haven't gotten fat! What's going on!?"

>The cause of it all...

>was what she had put in her brassiere to begin with!
>Her tits!!

p8
>If you keep wearing bras that don't fit you
>something that terrifying can happen~
>...

>It's got nothing to do with losing weight or being in your growing period.
>Eh...?

>Additionally, it can cause the Cooper ligament that supports the breasts to hurt.
>Cooper ligament (breast support ligament)
>A collagen fascicle which connects the milk glands with the pectoralis major muscle. It supports the bust upwards.

>You talk about size, but...

>My Mom's always bought them for me up until now...
>This one might be good~
>In that case!

p9
>Let's take your measurements!!
>Mesurements!!

>Hah
>I'm sorry!!
>What a weirdo...

>This is our fitting room.

>It's not that different from a tailor's fitting room.
>Yes! Exactly!

p10
>Here's a petticoat for those who come to the store in one piece dresses
>and some deoderant for you to use!
>>Petticoat
>Th-Thanks...

>Take off your clothes.
>Once you're ready, please call me with this chime.
>Take off!?

>I-
>I gotta be nude?

>Don't worry. I can take your measurements with your underwear still on!
>That way's more popular!
>Is that so...

>Of course, if you prefer to be naked, that's up to you!
>Well then, take your time!
>Ah... right...

p11
>Breast size, huh... I wasn't aware of that.

p12
>Ah... The customer from earlier...

>She's the one who was just in the store...

>Hah
>Um, could you close it please...
>Owah!

>Sorry.
>There we go.
>She came in!!

p13
>Can I come in, too?
>Bit late to be asking that!!

>Well, whatever.
>Go ahead.
>Thank you. You're so kind.

>I come her every day after school.

>Eh? Every day...?
>I collect underwear.
>H-Heh...

p14
>I'm Kosaka Geraldine.
>Just call me Gerry!

>Such cute underwear.
>Gerry-san...
>She introduced herself out of the blue.

>>Plain
>>Worn for several years

>Maybe I should get measured directly.

>Coming~

p15
>Excuse m-...
>Geh!

>Gerry! I told you not to come in when there's already a customer!!
>Sorara!
>She said it was okay!
>I don't really mind.
>It's more relaxing to have someone who's also half-naked with me...

>Geez. This is the last time, you hear!

>Just be glad that this customer was someone kind...
>Ah! Measuring tape!

>Can I measure her size?
>Of course you can't!!

p16
>Learn some common sense!
>I don't mind.
>Let's just get through the measuring.
>Start with Gerry-san.

>Miss...

>That's
>a great idea!!
>Again!?

>This is a good opportunity, so I'll use Gerry as a model!

>Honestly... Be grateful to the customer!!
>Thank you, miss~<3
>A bunch of weirdos...

>Well then, excuse me.

p17
>We start with the "underbust".
>Gerry's is 73cm.

>Next is the "topbust".
>98cm.

>Under? Top?

>[*When measuring breasts, drop your arms to the side without lifting them up so that the size doesn't change.]
>>Top bust
>>Underbust

>The underbust is the base of the breasts
>whereas the topbust is the bit that sticks out the furthest.

>So you measure two different places...
>Ooh...

p18
>The difference between the top's 98cm and the under's 73cm is 25cm.
>Which means Gerry's size is G75.
>>Top (98) - Under (73) = Cup (25)
>>A cup size of approximately 25cm is G-cup.
>>Others: C-cup is approx. 15cm, D-cup is approx. 17cm and so on.
>G75!

>Eh? You've gotten bigger again.
>That size is pretty unusual for a high schooler.
>Ehe! So I'm rare!?
>Gerry-san is a G-cup...

>Your underbust is 66.5cm.

p19
>Now, please bow down 90 degrees.
>Bow?

>Aren't you gonna measure my topbust?

>Since you're in the nude, miss, we'll be measuring your topbust in a different way.
>Eh...

>It's a good idea!
>She seems lively...

>L-Like this?
>Yes, just like that.

>Let's see.
>Topbust is 76.5cm.

p20
>The difference between your under is 10cm, so your size is A65.

>A65...

>I'm... an A-cup...

p21
>Ah. Erm...
>I'm really happy to learn things about my body I was never aware of before.
>I'm glad I worked up the courage to come here...

>Courage...
>!?

>S-So why did I have to bow down because I was in the nude?
>Did I say something weird...?

p22
>When you're in the nude, your top part sags down due to gravity.
>>Nude
>Top sags down
>Top positioning
>When wearing a bra, the top is supported in the right place.
>>Wearing a bra

>You can also measure while using your hands to support your breasts in place of a bra.
>I see...

>Well then, miss, do you have any color requests?
>Color...?

>Shall we try some on?
>Some undies!
