Quick Answer

Order the Bridget Bikini in the size that matches your hip measurement, then use the fit checks below to confirm it. If you are between sizes or prefer more coverage, size up. If you want a closer, no-shift fit, size down only when the fabric has enough stretch.

Start With Hip Measurement, Not Waist

Bikini briefs sit at or below the hip, so your hip measurement is the most reliable starting point. Measure around the fullest part of your hips and seat, keeping the tape level and snug but not tight. Then compare that number to the size chart for the specific style you are buying. Two bikinis from the same brand can fit differently, so check each product's chart rather than assuming one size carries over.

  • Measure over light clothing or bare skin, not over jeans.
  • Keep the tape parallel to the floor.
  • If your hip measurement lands between two sizes, size up for comfort.
  • Re-measure every few months if your weight or activity level changes.

Fit Checks That Matter More Than the Label

Once the bikini is on, check three things: the waistband should lie flat without rolling, the leg openings should not cut into your skin, and the back should stay in place when you sit, stand, and walk. If you have to tug the back down after a few steps, the size or rise is wrong for you. If the front pulls down or the sides dig in, the brief is likely too small.

  • Waistband test: slide one finger under the band. If it digs in, size up.
  • Leg test: a visible red line after 10 minutes means the leg opening is too tight.
  • Movement test: sit, stand, and take five steps. The brief should not ride up or shift.
  • Coverage test: check that the back covers what you want it to cover when you move.

Match the Rise and Cut to Your Routine

A bikini cut sits lower on the hip and offers less coverage than a brief. That makes it a good choice under low-rise jeans, skirts, and dresses, but a less ideal choice if you prefer full seat coverage or wear high-waisted bottoms. The U2762 Serena Bikini is a mid-rise style with a stretch lace back and a soft geometric pattern at the front, which makes it a useful comparison point if you want a slightly different look and feel from the Bridget.

  • Low-rise bottoms: a bikini cut usually works best.
  • High-rise bottoms: a brief or high-cut style may sit better.
  • Active days: look for a style that stays put when you move.
  • Lace or textured backs: check that the texture does not irritate your skin under fitted clothing.

Final Sale Changes the Math

Several Fit Fully Yours panties are listed as final sale, which means no returns and no exchanges. That makes getting the size right the first time more important than usual. Read the product page carefully before ordering, and if you are unsure between two sizes, choose the larger one unless the fabric is very stretchy. If you are shopping for a style that is discontinued, confirm the size is still available before you commit.

  • Check the return policy before you add to cart.
  • Buy one size up if you are between sizes on a final sale item.
  • Confirm your size is in stock, since final sale items may not be restocked.

Decision Rules for Choosing Your Bikini Size

  • If your hip measurement is between two sizes: Choose the larger size, especially on a final sale item where returns are not available. Comfort beats a snug label.
  • If you want less coverage under low-rise clothing: A bikini cut like the U2642 Bridget Bikini or U2762 Serena Bikini is designed for that lower rise. Match the rise to your bottoms, not the other way around.
  • If you need a size outside the Bridget range: The U1012 Maxine Brief covers S through 5XL, so it is the better starting point when your size is not listed for the Bridget. Check the size list before you fall in love with a style.
  • If you are unsure about a final sale style: Confirm the return policy and your size on the product page before ordering, since final sale means no returns or exchanges. No returns means no room for guessing.

Fit Fully Yours Bikini and Brief Options

  • U2642 Bridget Bikini: MAUVE PLUM: The U2642 Bridget Bikini in Mauve Plum is a final sale panty available in sizes S, 2XL, and 3XL. If you wear a common middle size like M or L, this style may not have your size, so check availability before you plan around it.
  • U1012 Maxine Brief: VIOLET: The U1012 Maxine Brief in Violet is a final sale panty offered in sizes S, M, L, XL, 2XL, 3XL, 4XL, and 5XL. This is the widest size range among the listed options, making it a practical choice if you need a size the Bridget does not offer.
  • U2762 Serena Bikini: SUGAR ROSE: The U2762 Serena Bikini in Sugar Rose is a mid-rise bikini with a stretch lace back and a soft geometric pattern at the front, available in S, M, L, XL, 2XL, and 3XL. The mid-rise cut sits higher than a classic bikini, which can suit you better if you want a bit more coverage without moving to a full brief.
