Quick answer
For the Kappa Sig Non-Personalized Pinstripe Baseball Jersey, start with your normal t-shirt size for a clean, classic fit. Size up one if you plan to layer it over a hoodie or want a looser, modern drape. Because these jerseys cannot be personalized and only limited sizes are available, check the size selector before you commit.
How a baseball jersey is supposed to fit
A baseball jersey is not a t-shirt. It is cut to sit slightly away from the body so it moves when you raise your arms, and the shoulder seam often lands a little lower than a standard tee. That extra room is intentional: it keeps the jersey from pulling across the chest during a game, a chapter event, or a long day on campus.
The practical target is a shoulder seam that sits at or just past your natural shoulder point, a body that skims without billowing, and a hem that covers your waistband when you stand. If the jersey is tight across the chest or the armholes bite, you are at least one size too small. If the fabric hangs past mid-thigh or the sleeves swallow your hands, you are at least one size too big.
Measure a jersey you already like
The most reliable way to choose a fraternity jersey size is to measure a top you already wear rather than guessing from height and weight. Lay a comfortable t-shirt or jersey flat, then measure three things: chest from armpit to armpit, body length from the highest shoulder point to the hem, and sleeve length from the shoulder seam to the sleeve edge.
Compare those numbers to the size selector on the product page. If you are between two sizes, decide based on how you will wear it. For a fitted look, choose the smaller size. For a relaxed look or layering, choose the larger size. The Kappa Sig Pinstripe Baseball Jersey is made from 100% breathable polyester, so it will not shrink much with normal washing, but it will drape differently over a hoodie than over a bare torso.
Layer it or wear it solo
Solo wear is the simplest case: your normal size gives you the intended silhouette. If you want the jersey to read as a statement piece over a plain tee, stay true to size. If you want it to feel like a light outer layer, go up one size so the fabric does not cling to the shirt underneath.
For cold-weather layering, think about what goes under the jersey. A crewneck sweatshirt adds noticeable bulk at the chest and shoulders, so a jersey that fits perfectly over a t-shirt may feel restrictive over a sweatshirt. The Kappa Sig Athletic Crewneck is a natural companion for game days and chapter meetings, but it is a midweight layer. If you plan to wear the two together, size up the jersey.

Sizing when the jersey is a gift
Gift sizing is harder because you cannot try it on. Ask for one number: the chest measurement of a jersey or t-shirt the recipient already wears and likes. That single measurement is more useful than height, weight, or a guess based on other apparel.
If you cannot get a measurement, choose the middle of the size range rather than the extremes. A slightly roomy jersey is more forgiving than a tight one, especially for a piece that is meant to be worn over other clothing. Keep in mind that this jersey cannot be personalized, so the size is the main decision you are making.
Caring for the fit you chose
Fit is not only about the size you order; it is also about how you wash and store the jersey. Turn it inside out, wash cold, and avoid high heat in the dryer. High heat is the fastest way to change the shape of a polyester jersey.
Hang or fold the jersey flat rather than stretching it over a hanger with sharp shoulders. If the jersey develops wrinkles, a low tumble or a short steam is safer than a hot iron directly on the fabric. Good care keeps the pinstripes crisp and the fit consistent season after season.
Decision rules for choosing your jersey size
- You wear it solo, fitted look: Order your normal t-shirt size. The jersey is cut to sit slightly away from the body, so your usual size gives you the intended classic silhouette. Best default if you want a clean, game-day look.
- You wear it over a hoodie or sweatshirt: Size up one. A midweight layer like the Kappa Sig Athletic Crewneck adds bulk at the chest and shoulders, and the jersey needs room to move without pulling. Size up if layering is your main use case.
- You are between two sizes: Choose the smaller size for a fitted look or the larger size for a relaxed drape. Check the size selector first because limited sizes are available. Decide by how you will wear it, not by the number alone.
- You are buying it as a gift: Ask for one chest measurement from a jersey or t-shirt the recipient already wears. If you cannot get one, choose the middle of the size range rather than the extremes. A slightly roomy jersey is more forgiving than a tight one.
