Size Guide + Fit Tips

1. Under Bust / Chest Measurement Using a soft measuring tape, bring the tape across your back under each arm, around the front and measure just below the bust (a good guide is where your bra strap clasps). 
2. Full Hip Measurement Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.
3. 
Thigh Measurement Measure around the fullest part of thigh keeping tape parallel with floor.

 

 

BETTY'S FIT TIPS

In general, Betty Designs endurance (swim/bike/run) products are designed with a "race fit". This means garments are supposed to be worn tight to the body. We do not recommend customers go up a size as it will compromise the performance features. Race fit does not mean extra tight. It means it IS tight, but is supposed to be that way. We use fabrics that are non-binding + contain 4-way stretch for comfort. No matter your size, our cycling, triathlon + swimsuits are meant to fit tight. The more they hug your body, the less chance of chafing, flapping fabric, drag in our swimsuits + less chance of irritation from fabrics rubbing in the incorrect areas. Betty believes that a Race Fit looks good on every size body. Yes. We are serious about that. Try us on for (your correct) size and see how it feels.

 

Betty Fit Fact: Garments that fit the body properly are more flattering than ill-fitting ones.
 
DO BETTY DESIGNS PRODUCTS RUN "TRUE-TO-SIZE"?

CYCLE: Our cycling items fit a tad on the bigger size. In general if you are typically a 2-4 and wear size S in our triathlon items you should go down to size XS in our cycle jerseys, bibs + shorts.

TRI: Our triathlon items fit "true-to-size", but a tad tight. If you generally wear M in most workout wear and are used to wearing clothing that fits on the tighter size go for your "true size". If you don't like things really tight, go up a size.

SWIM: Our swimsuits fit a tad on the small side. This being said, we suggest you go up a size from your tri size in our bikinis. One pieces are a bit more challenging. There are a lot of factors in how a one piece fits depending on your shape, but keep in mind the one piece swimsuits should be a little hard to get into and feel "really tight" out of the package. Not kidding! As you swim the thin straps will "give" a smidge and become more comfortable. If you pull on this suit easily and it gaps slightly at your collarbone area, it's too big!

RUN: Our run items (racerback tanks + bras) fit a tad on the larger side. If you typically wear a M, go down to size S. Our bras are made to support A + B cups. If you are bigger than that, you may need to layer over your favorite bra for high-impact activities.
