Criss Cross One Piece Swimsuits

What a Criss-Cross Back Is

A criss-cross back one-piece swimsuit runs the straps into an X between the shoulder blades — the crossing point sits where the two straps meet, and most styles tie or adjust there. Cross back, crisscross, and X back name the same construction.

What the Pool Carries

• Tie-back criss-cross — the straps cross and tie at the mid-back, fully adjustable.
• Adjustable-loop X-backs — the crossing sits on a loop you can tighten or loosen.
• Solids and prints — the crossing is the constant; the surface varies.

45 styles, from about $33.

Cross Back vs Racerback

The two secure backs are compared a lot, and they are different constructions:

• Cross back — the straps cross, and most styles adjust at the crossing. You can tighten or loosen the back.
• Racerback — the straps merge into a fixed Y above the waist. No crossing, no tie; the armholes sit high.
• The practical difference — cross back is adjustable to your fit; racerback is set and stays that way.

How to Shop This Collection

• Decide how much adjustability you want — tie-back for a dial-in fit, loop for set-and-forget.
• Check the strap width — wider straps sit easier on the shoulder; thin cord ties are the usual culprit behind chafe.
• Check the cup construction for bust support — the back anchors the suit, the cups carry the bust.
• Pair with an open-back cover-up if you want the X visible.

Quick Answers

Q: Does a criss-cross back give more support? A: The crossed, adjustable straps anchor the top of the suit more securely than straight set straps. Bust support still comes from the cups — pair with lined or structured cups for everyday support.

Q: How do I tie the back? A: Cross the straps at the mid-back, just above the waist, bring the ends around, and tie a double knot with a finger of slack so you can re-tighten after the suit gets wet.

Q: Is it good for swimming laps? A: Yes — the crossed, adjustable back is one of the most common competitive-swim constructions because it stays put.
