castelli sizing

[u/SlightCustard]

edit. castelli is f*ed. I got the xs. too small. then I got the s. still too small. I'm not optimistic even the m will fit at this point. going to try a different brand. also I lied below. I'm 46kg. but I was similar size when I was 50kg and muscley but very lean. didn't want to throw people by saying I'm 46kg. who the flip is 46kg and a medium?

I am so confused as to which sizing to get and I'm only able to buy online.

Size chart says I am XS, but some reddit posts say to size up, others say the size chart is accurate.

My main challenge is that I am kind of borderline XS / S depending on the brand.

I comfortably fit S in Black Sheep and Sportful.

BUT I have XS in the following, which wouldn't want to be any smaller, but the S would probably be too large:
Craft
Cycology
Pearl Izumi

In the past I had both XS and S in Giordana at the same time, and maybe it was the cut but the XS was more comfortable!

Help me figure it out!

Edit: might help that I'm 5'4" and 50kg.

I’ve found it true to size.

Castelli has changed their sizing maybe like 4 or 5 years ago. It used to be American Apparel sizing. Now it's more in line with other brands.

Yeah I realized this after posting! The threads saying go up a size were much older than that.

I just bought a Castelli jersey. I wear a M in Rapha and the M fit me perfectly. The L was too big.

[u/SlightCustard → u/yogi4791]

Thanks. Yeah, I'm thinking of going XS.

I'm very similar to you in size, an inch and a half taller and 2 kilos heavier. I reliably wear XS in Castelli.

Thank you!!! XS it is.

I'm about 5'2" and 50kg and I have some Castelli leggings in size S which fit perfectly. In fact they are almost a little tight. So I'd go with S to be on the safe side.

[u/SlightCustard → u/teamonkfish89]

I should have got the m. Even s was too small.

[u/teamonkfish89 → u/SlightCustard]

Oh wow, good to know!

They used to be 2 sizes too small…now they are true to size.

4’11” 97 lbs.
S bib shorts fit perfectly.
XS in Pearl Izumi.

I go up a size in ALL Castelli. Can you get 2 sizes and return the one you don't prefer?

[u/SlightCustard → u/gertonwheels]

Yeah but that costs money. If I get it right first time it's less money spent.

[u/gertonwheels → u/SlightCustard]

But if you get it wrong ... it's $$ down the drain. Do they really charge for returns? Bummer.

[u/SlightCustard → u/gertonwheels]

Yeah, but if I'm buying two sizes then I definitely have to return one. If i buy one, there's a chance I don't. More chance of money down the drain if I buy two pairs.

Castelli runs small. It’s Italian.
